Coupon code field. What brands are testing.

What it is

The promo-code box serves two kinds of shopper at once. One already has a code and wants somewhere obvious to put it. The other has no code, sees an empty box, and may leave the page to go looking for one. How visible the field is decides which of the two the page favours.

Almost every experiment in this group sits in the cart or the cart drawer; a one-off is in checkout.

The direction is open. Brands are testing both ways — hiding the field and opening it up — and none of these has a settled direction yet. This page describes what is being tested, not what has been found.

What brands tried

The experiments in the record fall into a few themes, all seen between May and October 2026. No brand is named in this section.

Hiding against showing. Most experiments are about this. On one side: the code box removed from the cart drawer, removed from checkout but kept in the cart, or collapsed behind a toggle. On the other: the field opened by default, with the input and an Apply button in plain view.

Restyling the collapsed row. A couple kept the field collapsed but changed how the row looks or reads — a squarer box with a percent icon, or a members-style “privilege code” label.

Explaining a rejected code. A one-off explained a rejected code in place: the code was only valid above a minimum spend, and the message said so next to the field.

Because both directions are being tested at the same time, the useful question for your own cart is which shoppers you are designing the field for, not whether to have one.

What this page does not tell you

• Whether it works. There are no outcome rates here. Outcomes — whether each brand kept the change — are tracked per experiment and are part of the Intelligence plan.
• Whether it will work for you. Your shoppers, prices and range differ from the brands in the record. A change one brand kept can fail on another site.
• Why a brand decided. One experiment is one brand's decision. The record shows what the brand did next, not the measured lift behind it.

ABSee is experimentation intelligence for ecommerce: a record of real experiments run by 1,150+ brands, with the page before, the version tested, and whether it was kept. How the record is built.

How to use this

Treat this page as evidence for a hypothesis, not an answer.

• Bring it to your own hypothesis. Name the problem on your own checkout that this change would address, and for which shoppers.
• Check the record for your category. Look for brands like yours, the version they tested, and what they did next.
• Test it yourself. Your own experiment is the only result that applies to your site.
