One flat delivery fee, buyers in 250 countries: picking the number

The order comes in overnight and the address is four thousand miles away. You are pleased for about ten seconds, until you open the postage calculator and discover the parcel you normally send for £2.10 costs £11.40 to get there. Your delivery fee was £3.50. Somewhere between the notification and the counter, a sale turned into a small donation. This is the moment every creator selling physical goods internationally meets sooner or later, and it is entirely survivable if you decide about it in advance rather than at the post office.

One number, wildly different journeys

The address form is generous: 250 countries are available, 33 of them with official region lists so states and provinces come from a proper list rather than free text, and Türkiye down to district level. That means the details reach you in a shape you can copy onto a label without guessing. What it does not mean is that the postage sorts itself out.

Your delivery fee is a single flat figure. Whether the parcel goes to the next town or across an ocean, the buyer pays what you named and you pay what the carrier asks. The difference between those two numbers is the whole game, and it swings by a factor of five or more once you leave your own country.

The uncomfortable truth is that no single number is right for every order. You are not looking for the correct fee. You are looking for a fee that comes out level or slightly ahead across the mix of orders you actually get, with an explicit decision about which orders you are willing to lose money on and which ones you would rather not take at all.

Guesswork against a stated number

Before any of this, most people were doing postage by conversation: a comment, a DM, a screenshot of a payment app, an address typed with a missing postcode. The comparison below is not really software against software. It is a stated number against an improvised one, and you can see how the checkout is presented on the payments page.

Blending a fee that survives contact with reality

The method below takes twenty minutes and works whether or not you use store.fan. It replaces a guess with a weighted average, which is the closest thing to a right answer that a flat fee allows.

1. 1List your three or four realistic destination groups: home country, neighbouring region, and the rest of the world. Add a fourth if one country dominates your audience.
2. 2Get a real postage price for your actual packed parcel in each group. Use the service you intend to use, including any tracking you promise.
3. 3Estimate the share of orders each group will take. If you have sold before, use your last twenty orders. If not, use where your audience actually reads you.
4. 4Multiply each postage price by its share and add the results. That weighted number is your honest break-even fee.
5. 5Round it to something human, then decide whether to sit slightly under it and absorb the difference as a marketing cost, or slightly over it for a buffer.
6. 6Set the figure as the delivery fee in the product editor and write your posting range into the product description in one plain sentence.
7. 7Revisit after twenty real orders and adjust. Your assumed mix will be wrong the first time; that is expected, not a failure.

A blended fee, worked through

Suppose you sell an A4 print. Domestic postage on your packed mailer is £2.10, the neighbouring region is £5.40, and everywhere else is £9.80. Looking at where your readers are, you expect roughly seven orders in ten at home, two in the region and one further out. The weighted sum is £1.47 plus £1.08 plus £0.98, which is £3.53.

Set the fee at £3.50 and you are level on average, ahead on the local orders and behind on the distant ones, which is exactly what a flat fee is supposed to do. Set it at £2.10 instead, because that is what you pay most often, and you are down around £1.40 on every order overall — invisible per sale, and £140 across a hundred parcels. The instinct to price from the parcel you post most often is the single most expensive habit in physical goods. Treat the shares here as an example of the arithmetic, not a claim about your audience.

The mistake most people make

The mistake is silence about geography. Creators set a fee, say nothing about where they post, and then feel obliged to honour every order that appears because refusing feels rude. One line — "I post worldwide; parcels outside Europe take three to four weeks" — converts better than vagueness and removes the awkward conversation entirely. If you would rather limit yourself for now, say that too. Nobody has ever been offended by a creator who was clear. There is a broader tour of what a storefront can hold on the features page, and the plan differences sit on pricing.

A flat fee is a blunt instrument, and blunt instruments work fine when you aim them deliberately. Weight your number by where your orders really come from, say where you post to, and the overnight order from four thousand miles away becomes a pleasure again instead of a sum you would rather not do.
