Adding Shop Pay and Google Pay buttons to the cart drawer raised conversion rate by 35% for snack brand Jackson's. Blend Commerce ran this A/B test in the brand's Rebuy Smart Cart. It reached statistical significance after two weeks, with revenue up 13%.

## Result

**+35% conversion rate**

- Conversion rate: +35%, statistically significant after two weeks.
- Revenue: +13%, and average purchase revenue per user: +12%.
- Express button clicks: Shop Pay +53% and Google Pay +40%. The source also reports Apple Pay clicks up 60%.
- The variant was set live permanently.

## Control

The Rebuy Smart Cart drawer had no express payment buttons.

## Variant

Shop Pay and Google Pay buttons were added inside the cart drawer.

## Why it likely won (our reading)

- Most of the brand's customers were already paying with express methods, so the buttons fit existing habits.
- Putting them in the drawer lets shoppers pay without opening the cart page or filling in checkout forms.
- Snacks are a low-risk, often repeat purchase, so a faster route to pay may be all many shoppers need.

## Caveats

The test ran for two weeks and reached statistical significance, but sample size was not shared. Results are reported by the agency that ran the test.

## How to run this test

- Hypothesis: If we add express payment buttons to the cart drawer, then more shoppers will complete their order because they can pay in one tap without filling in checkout forms.
- Primary metric: Conversion rate
- Guardrail: Average order value
- Guardrail: Cart drawer upsell take rate
- Guardrail: Revenue per visitor
- Who should test it: Shopify stores using a cart drawer where most buyers already pay with Shop Pay, Apple Pay or Google Pay. It may help less for high-price items where shoppers want to review the order carefully.
