Shipping is the one added cost sometimes knowable before checkout. We measured how often it actually is: 283 of 390 offers, and the split by search type is the interesting part.
Between two offers a few dollars apart, shipping usually decides which is actually less expensive. It is also the added cost most often visible before checkout, which makes it the one worth resolving while you are still comparing rather than after you have chosen.
Tax and mandatory fees generally cannot be resolved in advance, for reasons covered in our guide on comparison totals. Shipping frequently can, which is why it is the component this site works hardest to confirm.
Free delivery is almost never a property of a product. It is a condition attached to an order, and the condition is what you have to check.
| Condition | What it depends on | Does it apply to you? |
|---|---|---|
| Order threshold | Basket subtotal, often before tax | Only if this item alone clears it |
| Membership | A paid subscription to that retailer | Only if you already pay for it |
| Region | Distance from a fulfilment centre | Varies by your address, not the listing |
| Delivery speed | The slowest option offered | Free is rarely the speed shown first |
| Promotional window | A date range, sometimes unstated | May have ended before you check out |
The threshold condition deserves particular attention, because it can reverse the answer entirely. Suppose one retailer lists an item at 44 dollars with a 6 dollar delivery charge, and another lists the same configuration at 47 dollars with free delivery above 45. The item prices say the first retailer wins by three dollars. The delivered figures say the second wins by three.
No amount of comparing item prices reveals that, because the deciding number is not attached to the item. It is attached to the basket, and it only exists once the basket exists.
This is also why adding a small item to reach a threshold is sometimes rational and sometimes a trick played on yourself. If the filler item is something you would have bought anyway, the threshold is genuinely worth clearing. If it is not, you have spent money to avoid a delivery charge, which is the same money.
We measured this against a fixed cohort of 50 United States queries on 21 August 2026, which returned 390 offers. Of those, 283 carried an explicit mandatory shipping charge from a dedicated provider field — not a delivery date, not a conditional promotion, an actual figure. That is 73%.
The split by search type is the part worth knowing. Broad category searches returned confirmed shipping on 193 of 236 offers, or 82%. Exact-model searches — where someone has already chosen the product and is deciding where to buy it — returned it on 80 of 135, or 59%.
That is the opposite of useful. Delivery cost matters most at the exact-model stage, where two listings of the same machine are a few dollars apart, and that is precisely where it is least often known.
| Query type | Offers | With confirmed shipping | Share |
|---|---|---|---|
| Broad category | 236 | 193 | 82% |
| Exact model | 135 | 80 | 59% |
| Marketplace-heavy | 19 | 10 | 53% |
| All | 390 | 283 | 73% |
Two retailers charging the same delivery fee for five-day and next-day service are not offering the same thing. For a gift or a replacement for something that has broken, the faster option may be worth more than the price difference between the retailers.
Comparing on price alone quietly assumes delivery speed is equivalent. It rarely is, and the assumption is never stated — it is simply built into the act of putting two numbers side by side.
Return shipping is the cost that only matters when things go wrong, which is exactly why it is left out of comparisons. Free outbound delivery and paid returns is a common pairing, and the return charge is often larger than the outbound one would have been.
For anything where fit, compatibility or condition is uncertain — clothing, parts, refurbished electronics — the return policy is a bigger financial variable than the delivery charge. A retailer three dollars more expensive with free returns is usually the better purchase on anything you might send back.
Check who pays for the return, whether a restocking fee applies, and how long the window is, before you compare delivery charges. On a genuinely uncertain purchase, that ordering is the right one.
A delivery cost confirmed yesterday is a fact about yesterday. We stop presenting a confirmed total as a total once it passes a day old, not because the number is certainly wrong, but because a stale figure sitting beside a caveat gets read as the current figure. A caveat next to a number loses to the number.
When you compare manually, apply the same rule to anything you noted earlier in the week. It is a reason to look again, not a number to act on.
