**Answer.** Yes, and it is common: 40 of the 73 tracked mobile checkout apps with vision text (55%) surface a promo, coupon, or discount-code field [1]. That makes the promo field the single most common checkout element after the pay button in this corpus. Because it comes from prose descriptions, 55% is a directional lower bound.

> 40 of 73 tracked mobile checkout apps (55%) show a promo or discount-code field — the most common element after the pay button, Lazyweb Research, July 2026.

## The finding

Of the 73 checkout apps with readable vision text, 40 mention a promo, coupon, or discount-code field — about 55% [1]. No other checkout element besides the pay button itself appears in more apps in this corpus, which makes the promo field effectively a default rather than an edge case.

## How to apply this

A promo field is a two-sided decision: it lets deal-seekers redeem, but an empty box can prompt users to leave and hunt for a code they do not have. Given that 40 of 73 peers show one [1], the market default is to include it — but placement matters. If you show it, keep it collapsed or de-emphasized so it does not invite abandonment, and only expand it when a code is applied. If your funnel data shows checkout leakage right at the promo row, that de-emphasis is the first thing to test.

## Caveats

The 55% figure is an ILIKE keyword match ('promo', 'coupon', 'discount code') over prose vision descriptions across 73 of 77 checkout companies [1]. It undercounts apps that use non-matching wording and cannot distinguish a prominent field from a collapsed link. Sample is small (73 apps) and iOS-weighted; do not extend the percentage to web checkout.

## The numbers

| Stat | Computed from |
| --- | --- |
| 40 of 73 apps (55%) mention a promo/coupon/discount-code field | promo_code_prevalence (40/73 = 54.8%, rounds to 55%) |

## Methodology

Universe: 169 canonical checkout screens across 77 tracked mobile apps. Method: keyword match over prose vision descriptions for the 73 companies with vision text, July 2026. Caveat: directional lower bound; cannot distinguish prominent field from collapsed link.
