How to read an Amazon delivery estimate before you promise an eBay delivery date

How do you read an Amazon delivery estimate?

An Amazon delivery estimate is a promise about one offer, delivered to one address, for an order placed before a cut-off time. It tells you when Amazon or the seller expects the parcel to arrive, not when it will be dispatched. To use it well, you need to read all of its parts: the date or range, the "order within" countdown, the delivery location, the seller and whether the item is in stock now or only later.

eBay sellers look at Amazon delivery estimates for several reasons: to plan when stock bought from Amazon will arrive, to understand the delivery speed buyers are used to, and to compare products before listing. Whatever the reason, the same rule applies before you turn any date into a promise on eBay: allow for the slowest normal case, not the best one.

What does each part of the estimate mean?

If the seller is a third party, the offer may be fulfilled by Amazon or by the seller itself, and the two can behave differently. Our guide to FBA vs FBM offers explains what each means for delivery dates.

Why does the same product show different dates?

• The delivery address. Amazon calculates the estimate for the postcode or ZIP code you have selected. Change it and the date, and sometimes the offer, can change. Our guide to why the delivery postcode changes what you see covers this.
• The time of day. An order placed just after the cut-off may arrive a day or more later.
• The day of the week. Weekends and bank holidays stretch the gap between order and delivery for many offers.
• The offer in the buy box. If a different seller wins the buy box, its delivery promise replaces the previous one.
• Stock location. Items held far away, or not held at all, take longer.
• Busy periods. In the weeks before Christmas and around sale events, estimates lengthen and can slip after you order.

What does eBay's policy say about buying from Amazon?

One rule needs stating plainly. eBay's drop shipping policy says that 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, such as Amazon, that ships directly to your buyer is not allowed. The wording is on eBay UK's drop shipping page. An Amazon estimate is therefore most useful to an eBay seller for planning stock you will hold and dispatch yourself, and for understanding what buyers expect. You remain responsible for every delivery promise you make on eBay.

How does eBay decide that a parcel was late?

On eBay UK, your listing's estimated delivery date comes from your handling time and the postage service you choose. With tracking, an item counts as late if the delivery scan is after the latest estimated delivery date and there is no carrier scan within your dispatch time. Late delivery has no minimum for Above Standard, but Top Rated sellers must have no more than 5 late deliveries or 3% of transactions. These rules are in eBay UK's seller performance policy, and our guide to the eBay late delivery rate explains each case.

In the US, the FTC's mail order rule says that if you state a shipping time you must be able to meet it, and if you cannot, you must ask the customer to agree to the delay or cancel and refund promptly. In the UK, goods sold online by a business must be delivered within 30 days unless agreed otherwise.

How do you turn an Amazon estimate into a plan you can keep?

Use the estimate as one input, then build in the delays it leaves out.

1. Check the estimate with your own address selected, at the time of day you normally order, on a weekday and on a Friday.
2. Take the later end of any range as your planning date.
3. Add your own processing time: the time to receive, check, pack and post the item.
4. Add the transit time of the postage service you will use on eBay.
5. Set your eBay handling time so that the slowest normal path still dispatches within it.
6. Re-check before busy periods, when every part of the chain slows down.

Example (hypothetical): you restock a product by buying a box of units from Amazon to keep at home. On a Thursday evening the page shows delivery "Saturday to Monday" to your postcode, with an order-within countdown that has already passed. Plan on Monday, or Tuesday to be safe. If you list new units only once the box has arrived and set a handling time of 1 business day with a 2 day postage service, every promise rests on stock you already hold, which is the point.

Do estimates work differently on amazon.co.uk and amazon.com?

The parts of the estimate are the same, but the spread of dates differs. On amazon.co.uk the estimate is set by your postcode, and most of the mainland is served on similar timescales, though remote areas, the Highlands and islands, and Northern Ireland can take longer. On amazon.com it is set by your ZIP code across a far larger country, so the gap between a buyer near a warehouse and one on the other side of the country can be several days.

For US sellers, that means one estimate checked at your own ZIP code says little about delivery to buyers in other states. For UK sellers, it means checking a remote postcode as well as your own before you rely on a date for planning.

What should you record when you check an estimate?

If you use Amazon estimates to plan stock, a short log turns impressions into evidence. For each check, note:

• the date and time you checked, and the postcode or ZIP code selected;
• the estimate shown, including both ends of any range;
• who sold and who dispatched the offer;
• for orders you placed, the date the item actually arrived.

After a few weeks you can see how often the estimate held, how often delivery came at the later end, and which days of the week slip. That record is a far better basis for your own handling time than any single estimate.

Which warning signs should make you wait?

• The estimate is a range spanning a week or more.
• The page says the item is usually dispatched in several days or weeks.
• The only offer is from a third-party seller with a long delivery window.
• The date jumps every time you refresh or change address.
• The page shows a later availability date rather than stock now.

Any of these means the date is a forecast, not a plan. Wait until the stock is with you, or choose another product.

How do Prime and paid delivery affect the estimate?

Membership and paid delivery options can show a faster date than the free option. Make sure you read the date for the option you will actually choose. Our guide to Amazon Prime delivery and eBay handling time explains how faster delivery dates relate to what you promise on eBay.

A checklist before you rely on an Amazon date

• The delivery address shown is the one the parcel is going to.
• You ordered before the cut-off, and you planned on the later end of any range.
• You know who sells and who dispatches the offer.
• The item is in stock now, not "usually dispatched within" a period.
• Your eBay handling time covers your own slowest normal processing, and you list only stock you can dispatch within it.
