Required
Never make green claims you cannot prove
ECM-49 EU lawNever 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.
Say how you check that reviews come from buyers
ECM-50 EU lawWherever 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.
Never fake, buy or hide reviews
ECM-51 EU, US lawNever 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.

Apply discounts on the server in one fixed order
ECM-36Apply 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.
Limit each coupon per customer instead of per account
ECM-37Enforce 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.
