Marks and Spencer will deliver free if you spend £75. Uniqlo asks £50. ASOS asks for £9.95 once, and then delivers free for a year. Those look like three prices for the same service. They are three different purchases, and only one of them is about delivery.
The three models on offer
Three structures are visible in the UK clothing market: a spend threshold, a paid membership, and a gate that makes free delivery a reward for having an account. Same vans, three jobs.
The thresholds cluster tighter than you would expect for a market this varied. H&M sets £40 and reserves it for members. Uniqlo sets £50. Marks and Spencer sets £75, the highest verified in the set.
The spend thresholds sit in a narrow band, and they are set against basket size, not against cost.
Nothing about a van explains that spread. The distance between £40 and £75 is a decision about what a normal basket looks like and how much bigger you would like it to be.
A threshold prices the order
A threshold works on the basket in front of you. It lifts this order and does nothing about the next one, which is why it has to be re-earned on every visit.
A spend threshold is a promotional mechanic. It says: add another item and the delivery is on us. It works on the basket that already exists, it is easy to model, and it is genuinely effective at what it does, which is moving average order value.
What it cannot do is anything about the visit after this one. A shopper who reaches £50 at Uniqlo on Tuesday arrives on the following Tuesday with the same decision to make and no accumulated reason to make it the same way. The lever resets. That is not a criticism, it is a description of the instrument: a threshold is activation spend that happens to be denominated in postage.
A membership prices the year
ASOS charges £9.95 once and delivers free for twelve months. That is a switching cost the shopper paid for voluntarily, and it changes where they start looking, not just what they add to this basket.
A paid delivery membership does something structurally different, and the difference is worth being precise about. ASOS Premier costs £9.95 a year and gives unlimited next-day and nominated-day delivery on orders over £15, plus free standard delivery on everything else. boohoo Premier is £9.99 for the year.
Once someone has paid, every subsequent purchase in the category starts from a different place. Every competitor now gets compared on price plus the delivery charge the shopper has already avoided. The retailer has been paid to install a reason to come back, which is an unusual trade.
A threshold has to be won again on every visit. A membership was bought once and works while the shopper is asleep.
ASOS states on its own page that Premier “pays for itself after just 2 orders with Next Day Delivery”. Read that as the retailer telling you what it thinks it is selling: the removal of a decision.
Which model you run is a positioning decision
The choice is not operational. A threshold suits a considered, infrequent purchase; a membership suits a category people buy from often, and only pays if they do. Picking one sets what your delivery promise is for.
The three models suit different businesses, and what decides the fit is purchase frequency.
The same capability, pointed at two different problems.
A threshold fits
- Infrequent, considered purchases.
- Baskets that can plausibly stretch.
- Categories where the next visit is months away.
A membership fits
- Frequent, low-consideration purchases.
- Shoppers who order many times a year.
- Categories where being the default is worth more than this basket.
Marks and Spencer at £75 and ASOS at £9.95 are not competing on the same axis, and a retailer copying either without asking how often its customers buy is copying the mechanic and missing the decision. A membership sold into a category people buy from twice a year is a discount with extra steps. Run a threshold in a category people buy monthly and the habit never gets built.
So the useful question before the next planning round is not what delivery costs to run. It is how often a good customer buys, and whether you would rather have a larger order today or a smaller one you can count on.
Where this argument is weakest
Three of eight retailers could not be verified, one of them the most interesting. Thresholds move, sometimes weekly, so treat these as a dated snapshot rather than a market map.
Everything above rests on what each retailer publishes on its own page, read on 3 August 2026. Three of the eight I set out to check could not be verified: ASOS’s non-member threshold, John Lewis’s thresholds, and Next’s standard delivery, which matters most because Next appears to run no spend threshold at all and to sell an annual scheme instead. If that is right it is the cleanest example of the membership model in the market, and it is the row I could not confirm.
These terms also move. Retailers change thresholds seasonally and around peak, so this is a snapshot with a date on it, not a stable map. The direction of the argument does not depend on the exact figures, but if you are going to quote £75 at anyone, check it first.
