Amazon Lightning Deal Prices and Coupons: Why They Should Not Set Your eBay Price
In short
Amazon lightning deal prices and coupon discounts are temporary: a lightning deal runs for a limited time or until its allocation sells out, and a coupon can be limited or withdrawn at any time. If you set your eBay price from them, your margin disappears when the offer ends. Price from the regular buy box price instead.
Key takeaways
- Lightning deals and coupons are temporary, so pricing an eBay listing from them can turn sales into losses when they end.
- The buy box usually shows the deal price during a lightning deal, so automatic repricers can follow it unless you set guards.
- Base your eBay cost on the regular Amazon price from price history, with coupons stripped out.
- Use a price floor, a minimum profit and a swing limit so large drops wait for your review.
- eBay does not allow listing an item and then buying it from another retailer that ships to your buyer, and you stay responsible for delivery.
Why shouldn't Amazon lightning deal prices set your eBay price?
Amazon lightning deal prices are temporary, so they make a poor base for an eBay price. A lightning deal is a short promotion on a single product, usually with a limited number of units at the deal price. When the time runs out or the units are claimed, the Amazon price goes back up, but your eBay listing keeps the low price until you or your repricer changes it.
Coupons cause the same problem more quietly. An Amazon coupon (often shown as a voucher on Amazon.co.uk) is a discount taken off at checkout, usually after you tick a box on the product page. It can end, run out or apply only to some customers, so the price you pay on your next order may be higher than the one you planned around.
The working rule is simple: build your eBay price on the price you can expect to pay most of the time, not the best price you saw this week. Every eBay sale is a promise to fulfil at whatever your cost is on the day the buyer orders.
One rule comes before any pricing. eBay's drop shipping policy says dropshipping, where you fulfil orders directly from a wholesale supplier, is allowed. Listing an item on eBay and then buying it from another retailer or marketplace that ships directly to your buyer is not allowed. You can read the policy on eBay.co.uk and eBay.com. Whatever your source, you stay responsible for delivery within the time stated in your listing and for the buyer's overall satisfaction, and eBay may remove listings, issue warnings, restrict activity or suspend accounts that break the policy.
How is a lightning deal different from a coupon or a normal price drop?
Amazon shows several kinds of low price, and only some of them last. The buy box is the main offer on an Amazon product page: the price and seller you get when you press Add to Basket (Add to Cart on Amazon.com). During a lightning deal the buy box usually shows the deal price, which is why any tool that reads the buy box will pick it up.
| Price type | What you usually see | How long it lasts | Use as your eBay cost base? |
|---|---|---|---|
| Lightning deal | Deal badge, countdown timer or a bar showing how much has been claimed | A short fixed window, or until the deal units are claimed | No |
| Coupon or voucher | A separate line or tickbox near the price; discount applied at checkout | Until the coupon ends or runs out | No: add the discount back |
| Event deal (Prime Day, Black Friday) | Deal badges across many products at once | The event days | No |
| Prime member price | A lower price shown only to Prime members | The length of the promotion | No |
| Subscribe and Save | A lower price for repeat deliveries | While a subscription is active | No |
| Regular buy box price | A plain price with no badge or timer | Until the seller changes it | Yes, after checking its history |
Subscribe and Save is a separate trap with its own quirks, covered in our guide to why the Subscribe and Save price is not the price to build an eBay listing on.
Sometimes a lower price is a real, lasting change: a newer model arrives, a seller cuts the price for good, or a new competitor joins the listing. A lasting drop has no badge or timer and holds steady for weeks. You only learn that by watching it, which is why price history matters more than any single reading.
How much can a deal price cost you? A worked example
Example (hypothetical numbers): suppose an item's regular Amazon price is £30, and a lightning deal drops it to £21 for an afternoon. The arithmetic is the same in dollars on Amazon.com. You want £4 profit per sale, and for this example we use a hypothetical all-in eBay fee rate of 15% of the sale price.
That 15% is not eBay's actual rate. Business seller fees vary by category, so check the current figures on eBay's selling fees page on eBay.co.uk, or the fee pages in eBay.com Seller Help if you sell in the US. In the UK, eBay says you must register as a business seller if you sell items you bought to resell, so private seller fee rules do not apply to this kind of selling.
To build fees into the price, divide your cost plus target profit by (1 minus the fee rate). Here that means dividing by 0.85.
| Line (hypothetical) | Priced from the £21 deal | Priced from the £30 regular price |
|---|---|---|
| eBay price | £29.41 | £40.00 |
| Fees at the hypothetical 15% | £4.41 | £6.00 |
| You receive after fees | £25.00 | £34.00 |
| Profit if your cost is £21 (deal still live) | £4.00 | £13.00 |
| Profit if your cost is £30 (deal ended) | Loss of £5.00 | £4.00 |
Priced from the deal, every order that arrives after the deal ends loses £5 in this example. Five such orders overnight turn a promising afternoon into a £25 loss, before any returns. Priced from the regular price, you are less competitive while the deal runs, but the deal itself never puts you into a loss.
Promoted Listings make the gap wider. In a general (cost per sale) campaign, the ad fee is a percentage of the total sale amount, including item price, postage and taxes, as eBay explains on its Promoted Listings page. That fee comes out of the same thin margin.
How do you spot a temporary price on Amazon?
Most temporary prices leave visible clues on the product page. Check for these before you accept any price as your cost:
- A deal badge such as "Lightning Deal" or "Limited time deal" near the price.
- A countdown or a claimed bar showing how long the deal has left or how much of it has gone.
- A struck-through reference price next to the current price, which signals a discount from a usual level.
- A coupon or voucher line with a tickbox. The headline price often excludes it, so check whether your figures assumed it.
- A Prime-only price that differs from the price shown to non-members.
- A price well below its history, even without a badge. Sudden drops are worth treating as temporary until they hold.
- The calendar. Large sale events bring many deals at once. Our article on the Prime Day effect on eBay sellers covers what to do before, during and after.
The price you see can also depend on the delivery postcode or ZIP code you check from, so always read prices at the same delivery location you plan around.
What price should you base your eBay listing on instead?
Your cost base should be a price you can realistically pay on any ordinary day. These steps get you there.
1. Find the regular price
Look at the item's price over several weeks rather than one reading. The level it returns to after each dip is your regular price. Our guide on how to read Amazon price history before you set an eBay price shows what to look for.
2. Strip coupons out of your cost
Calculate your cost without any coupon or voucher. If a coupon happens to apply when you buy, treat the saving as a bonus, not as margin you counted on.
3. Use the higher price during deal periods
While a deal is live, price from the regular price, not the current one. If the regular price has genuinely moved, wait until the new level holds before you follow it down.
4. Set a minimum profit floor
Decide the smallest profit you will accept per sale and work out the eBay price that protects it at the regular cost. Any automatic change below that price should stop rather than go live.
5. Recheck when the deal ends
When a deal sells out, the buy box can move to another seller at a higher price, or the item can show as out of stock. Read the page again after the deal window and update both price and quantity.
How do you stop a repricer from following a deal price?
A repricer is software that changes your eBay prices automatically when your source price moves. It is only as careful as its rules: if it reads the buy box during a lightning deal and applies your formula straight away, it lowers your eBay price to match the deal. It raises the price again when the deal ends, but every order taken in between is at the low price.
Whatever tool you use, look for these protections:
- A minimum price floor for each listing, so no automatic change can push it below a level you set.
- A swing limit that holds any change larger than a set percentage instead of applying it.
- A review step for held changes, so you can see whether a drop is a deal or a lasting change.
- Per-listing overrides for products you know go on deal often.
- A record of why each price changed, so you can trace a bad price back to its cause.
In Dropizon, every price push passes a price circuit breaker with a floor, a ceiling and an optional swing limit, along with a minimum profit floor in your pricing formula. Changes that trip a guard wait as holds for one-click review, and a reason is recorded for every push and every hold. The Dropizon documentation explains the formula and each guard.
What happens if the deal ends after your eBay buyer orders?
Your buyer agreed a price and a delivery date with you, not with Amazon. A change in your cost does not change what you owe the buyer, and eBay's drop shipping policy says the seller is responsible for safe delivery within the time frame stated in the listing.
- eBay Money Back Guarantee: buyers can report an item not received within 30 calendar days of the estimated delivery date. Sellers must respond within 3 business days, after which the buyer can ask eBay to step in. See the eBay Money Back Guarantee policy.
- UK consumer law: goods bought online from a business must be delivered within 30 days unless agreed otherwise, and the buyer can cancel up to 14 days after delivery without giving a reason. The details are on gov.uk.
- US FTC rule: if you state a shipping time, you must be able to meet it. If you cannot ship on time, you must ask the customer to agree to the delay or cancel with a prompt refund. Read the FTC business guide.
- Seller performance: eBay UK evaluates sellers on the 20th of each month, and Top Rated status allows a transaction defect rate of no more than 0.5%. The seller performance policy explains what counts. US sellers can find the equivalent standards in eBay.com Seller Help.
Every Amazon purchase is also made under Amazon's own Conditions of Use and Sale. Read them yourself before you buy, rather than relying on what any seller forum says about them.
What to do next
You can tighten your pricing against temporary Amazon prices in an afternoon:
- Sort your active eBay listings by recent price change and pick out any that dropped sharply in the last week.
- For each one, open the Amazon page and check for a deal badge, timer, coupon line or Prime-only price.
- Compare the current Amazon price with its history and note the regular level.
- Reprice any listing built on a deal or coupon so it covers your target profit at the regular cost.
- Set a price floor and, if your tool supports it, a swing limit on every listing before the next big sale event.
- Remove coupon savings from any spreadsheet or formula you use to calculate cost.
- Put a reminder in your calendar to recheck prices and stock the day after each major Amazon event.
Frequently asked questions
Do Amazon lightning deals come back on the same product?
Some products appear in deals more than once, but the product page does not tell you when, or whether, a deal will return. Treat every deal as a one-off event. Keep pricing from the regular price and let any deal you happen to catch be extra margin.
Should I lower my eBay price to match competitors during an Amazon deal?
Only if the lower price still covers your cost at the regular Amazon price. Competitors who priced from the deal may lose money or pause listings when it ends. Matching a price you cannot sustain means every sale during the deal carries a risk of loss.
Is the coupon discount included in the Amazon buy box price?
In most cases the coupon is shown as a separate line near the price and only deducted at checkout. That means the headline buy box figure is often the price before the coupon. Check the checkout total rather than assuming either way.
What should I do if an order arrives at a deal-based price after the deal has ended?
You still owe the buyer the item at the price they paid and within your stated delivery time. Decide quickly whether you can fulfil at a loss, and contact the buyer straight away if you cannot. Use eBay's cancellation process rather than leaving the order open, then fix the listing price so it does not happen again.
Can I buy stock during a lightning deal to sell later on eBay?
Buying stock and holding it yourself fixes your cost, which is different from pricing a listing from a deal you have not bought. Read Amazon's Conditions of Use and Sale first, because every purchase is made under them. In the UK, eBay expects people who buy items to resell to register as business sellers.
