The discount code message is removed and a short USP bar takes its place.

Simplified mockup drawn by LiftArchive from the shared screenshots.

Control

The cart carried a message about a discount code above the cart item. The rest of the page held the item, subtotal, checkout button, payment logos and a Back to Shop link.

Variant

The discount code message was removed. A slim bar with a support icon and a short USP sat above the cart item instead; everything else stayed the same.

Why it likely won

Our reading of the result, not the practitioner's claim.

Caveats: Although framed as removing one line, the image caption says the message was replaced with USPs, so two things changed. Sample size, test length and baseline revenue were not shared.

How to run this test on your store

Hypothesis
If we remove the discount code message from the cart and show a key USP instead, then revenue per session will rise because shoppers stop hunting for codes and focus on product value.
Primary metric
Revenue per session
Guardrails
  • Conversion rate
  • Discount code usage rate
  • Average order value
Who should test it
Stores that show discount code prompts in the cart but don't run code-led promos. If your traffic relies on influencer or affiliate codes, removing the prompt could confuse those shoppers.
