Build your stack in the buy box
It's Black Friday. Everyone's discounting.
The idea: Putting a build-your-stack picker (gifts unlock at 3 and 4 items) right under the subscription choice raises average order value without lowering conversion.
Only the outlined part is new. Everything grey is the same as A.
What’s different
The stack builder sits in the buy box
Add-ons are part of the main decision, not an afterthought below the fold.
Every item added unlocks something
10% at 2 items, 15% + travel tin at 3, 20% + tea sampler at 4.
Companions ship once
Only the gummies renew on subscription; the widget says so.
The test we’d run
Build-your-stack in the buy box vs 'Complete your routine' add-ons below it. Measure AOV and conversion.
