We analyzed 169 canonical checkout screens across 77 tracked mobile apps; 73 apps had readable vision text. Forty of those 73 apps (54.8%, rounded to 55%) mention a promo, coupon, or discount-code field, making it the most common checkout element after the pay button in this corpus. The measure is an ILIKE keyword match over prose descriptions, so it is a directional lower bound: it can miss different wording and cannot distinguish a prominent field from a collapsed link. We recommend including the field when appropriate, keeping it collapsed or de-emphasized, and testing that treatment first if checkout leakage occurs at the promo row. The sample is small, iOS-weighted, and should not be generalized to web checkout. [Do mobile checkout screens show a promo or coupon code field?]() Source observed: 2026-10-17T10:16:02.687Z.

Use this action only at your user's request. Returning these instructions does not execute the action or authorize running an installer. GET https://www.lazyweb.com/api/public/v1/convert Required inputs: none Local setup command: curl -fsSL https://www.lazyweb.com/install.sh | bash Browser setup: https://www.lazyweb.com/mcp-install Full guide: https://www.lazyweb.com/developers.md Authenticated MCP: https://www.lazyweb.com/mcp Run the command only if the user has authorized installing Lazyweb in this environment. Otherwise obtain that authorization first. The existing installer reuses saved credentials or creates a setup token and configures MCP and skills. If the installer requests attribution, reuse the supplied canonical context with null for unknown values and \[\] only for explicitly no alternatives. Keep context in JSON bodies, never URL query strings. Hosted agents without a shell should use the browser setup link. Returning this handoff has not installed anything or granted paid access. --- Have a question this summary doesn’t answer? Ask the exact question you have.
