'1 product away' extra 30% off in mini cart: +14.14% purchases
Commentary byLiftArchiveOur analysis, not theirsAdding a mini cart notice that one more product would unlock an extra 30% off lifted purchases by 14.14% for jewelry store Dorado Fashion.
Wingify Services ran the test, and it was published as a VWO case study.
It ran for 26 days on all devices.
- Purchases (visits to the thank-you page): +14.14%.
- The test aimed to raise average order value, but no AOV result was shared.
- The variant was then shown to all visitors.
The change
Mini cart adds a notice about unlocking an extra 30% off
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
After a shopper added one product, the mini cart showed no offer and no savings.
Variant
The mini cart showed the notice "You are 1 product away to get Extra 30% Off".
Why it likely won
Our reading of the result, not the practitioner's claim.
- The offer gives a clear reason to finish the order now and to add a second item.
- Showing the saving right after add-to-cart catches shoppers at a moment of intent.
- The team had seen confusion about total savings. A single, plain offer may have cleared that up.
Caveats: The goal was average order value, but only the purchase lift was reported, so the effect on order size and margin is unknown. Sample size and confidence were not shared.

How to run this test on your store
- Hypothesis
- If we tell shoppers in the mini cart that one more item unlocks a bigger discount, then more of them will complete a purchase and add items, because the reward is clear and close.
- Primary metric
- Purchase conversion rate
- Guardrails
- Average order value
- Gross margin per order
- Discount cost as a share of revenue
- Who should test it
- Stores with low-cost items that shoppers often buy in multiples, like jewelry or accessories. It is risky where margins are thin, since a 30% discount can cost more than the extra orders bring in.
Questions
Do 'buy one more' offers in the cart work?
They can. Here a mini cart notice about an extra 30% off with one more product raised purchases by 14.14%.
How big should a multi-buy discount be?
Large enough to be noticed, but check margin first.
Track margin per order as well as conversion, since deep discounts can erase profit.
Where should I show a bundle offer?
Right after add-to-cart, in the mini cart or cart drawer, is a strong spot because the shopper has just shown intent.
