What it is

An interactive builder lets the shopper pick their items and choose a pack size on a 2 / 3 / 4-pack slider, with the per-unit price, a running total saving and Most Popular / Best Deal labels updating live as they add.

Why it works

Letting the shopper assemble their own mix removes the risk of committing to items they might not like, and the live savings slider gamifies buying more, so a bigger, higher-value order feels like the shopper's own choice rather than an upsell.

How to test it

Hypothesis
A build-your-own-bundle with a live savings slider will lift average order value and units per order versus fixed pre-made bundles.
Primary metric
Average order value
Guardrail metric
Conversion rate, to confirm the builder does not add friction that stalls the purchase
