Boosting AOV with Collar and Sleeve Bundle Promotion on PDP


IF we promote a “Buy Collar, Get Off Sleeves” offer on the PDP THEN the average order value will increase BECAUSE customers feel like they're getting a bargain while making their product more unique, custom and desirable.
What We Changed
- Introduced a bundle promotion near the Add to Cart button.
- Added sleeve add-on option below size and variant selectors.
- Auto-applied discount when both items were in the cart.
- Displayed original price and discount clearly.
The Results
We dig through every data source to map what's actually broken. By the end, there's no confusion.

Click-through rate change
Average order value
Key Learnings
- The hypothesis was partially correct. AoV did increase, and more customers purchased the upsell.
- There was additional friction added and some users were confused by the offer, resulting in a drop in conversion rate.
- Recommendation: Run this exact experiment again with a redesigned upsell component that better explains the value.
- Declaring this test a winner because AoV and RPV increased.
