Collar and sleeve bundle offer on product page: +9.8% AOV
Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding a collar-and-sleeve bundle offer near the add-to-cart button lifted average order value 9.8% and revenue per visitor 0.6%.
Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library.
Conversion rate fell 4.0%, so the gain came from bigger orders, not more buyers.
- Average order value rose 9.8%, so shoppers who bought spent more, and more of them took the sleeve upsell.
- Revenue per visitor, the main goal, rose only 0.6%. The bigger orders were mostly offset by fewer buyers.
- Conversion rate fell 4.0% and add-to-cart rate fell 2.9%. Both are negative and point to added friction.
- Clicks rose 24.3% and click-through rate 23.0%, so the offer drew attention.
The change
The variant adds a sleeve add-on and a bundle discount offer by add-to-cart.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The product page had no bundle offer. Shoppers picked a size and variant and added the collar to the cart on its own.
Variant
A "Buy Collar, Get Off Sleeves" promotion sat near the add-to-cart button, with a sleeve add-on option below the selectors. The discount applied automatically when both items were in the cart, and the page showed the original and discounted prices.
Why it likely won
Our reading of the result, not the practitioner's claim.
- A clear money-off deal on a matching item gives shoppers a reason to add a second product.
- Showing the original and discounted price side by side makes the saving easy to see.
- The extra option near the buy button likely made the decision harder for some shoppers. Clean Commit noted some found the offer confusing, which fits the drop in conversion.
Caveats: Clean Commit did not share sample size, duration or confidence, and listed the outcome as a positive signal while calling it a winner. The revenue gain is small and conversion fell, so treat this as a modest win on order value.

How to run this test on your store
- Hypothesis
- If we offer a discount on a matching add-on next to the add-to-cart button, then average order value will rise because shoppers see a bargain that completes the main product.
- Primary metric
- Revenue per visitor
- Guardrails
- Conversion rate
- Add-to-cart rate
- Average order value
- Who should test it
- Stores whose products have a natural companion item, like a collar and sleeves or a case and strap. It probably won't help if the add-on feels unrelated, or if your buyers already struggle with too many options on the page.
Questions
Do bundle offers on product pages raise average order value?
They can. In this test order value rose 9.8%, but conversion rate fell 4.0%, so revenue per visitor barely moved.
Why would a bundle offer lower conversion rate?
An extra choice next to the buy button adds friction.
If the offer isn't clear, some shoppers hesitate or leave instead of buying.
Should the bundle discount apply automatically?
Auto-applying it, as this store did, removes the need for a code.
Make sure the page explains how the deal works so shoppers trust the price they'll see in the cart.
