# Promotions and claims

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [E-commerce and fulfilment](https://agentwranglers.se/playbook/ecommerce.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

> Apply discounts on the server in one fixed order, limit coupon abuse, and never fake urgency, green claims or customer reviews.

## Required

- ECM-49 [Never make green claims you cannot prove](https://agentwranglers.se/playbook/ecommerce/promotions-and-claims/unproven-green-claims.md) · 745 tokens · updated 2026-10-27
  Never call a product or the business green, eco-friendly, climate neutral or similar without proof of recognised excellent environmental performance. Never show a sustainability label that no certification scheme or public authority gave.
- ECM-50 [Say how you check that reviews come from buyers](https://agentwranglers.se/playbook/ecommerce/promotions-and-claims/review-verification-notice.md) · 932 tokens · updated 2026-10-27
  Wherever you show customer reviews to EU consumers, say beside them whether and how you check them. The check shows that each review comes from someone who bought or used the product. Mark a review "verified purchase" only when it is tied to an order.
- ECM-51 [Never fake, buy or hide reviews](https://agentwranglers.se/playbook/ecommerce/promotions-and-claims/no-fake-reviews.md) · 1,069 tokens · updated 2026-10-27
  Never write, generate, buy or commission reviews, and never pay or reward a review on condition that it is positive. Publish every genuine review, good or bad, under the same rules, and never threaten a reviewer.

## Recommended

- ECM-36 [Apply discounts on the server in one fixed order](https://agentwranglers.se/playbook/ecommerce/promotions-and-claims/discount-order.md) · 933 tokens · updated 2026-10-27
  Apply promotions in one documented order, such as line discounts, then order discounts, then shipping discounts, then tax. Write which promotions combine as data, and never let a line go below zero.
- ECM-37 [Limit each coupon per customer instead of per account](https://agentwranglers.se/playbook/ecommerce/promotions-and-claims/coupon-limits.md) · 821 tokens · updated 2026-10-27
  Enforce each coupon's limits on the server, with a unique constraint on its use per customer. Count a customer by normalised email, payment card fingerprint and delivery address, not by account alone.
