Adding express checkout buttons to the cart drawer brought Tuckernuck an estimated revenue uplift of about $355K a month. Domaine, the agency, ran this A/B test for the women's fashion brand, and it was published as a Visually case study. Before the test, shoppers only saw express payment options once they reached checkout.

## Result

**about +$355K a month (est.)**

- Revenue: about +$355K a month in estimated uplift. This is a projection, not measured revenue.
- Conversion rate, sample size and confidence level were not shared, so the size of the effect can't be checked.

## Control

The cart drawer showed the cart items and a standard checkout button. Express payment options only appeared on the checkout page.

## Variant

Express checkout buttons were added inside the cart drawer, so shoppers could pay with a saved wallet without going through the standard checkout first.

## Why it likely won (our reading)

- Shoppers who already use a digital wallet can pay in one or two taps from the drawer, which skips form filling.
- The drawer is where buying intent peaks, so putting the fastest path to payment there removes a step at the right moment.
- Fewer page loads between cart and payment leaves fewer chances to drop off, especially on mobile.

## Caveats

The monthly figure is an estimate, not measured revenue. Vendor-reported as a Visually case study; sample size, test length and statistical significance were not shared.

## How to run this test

- Hypothesis: If we add express checkout buttons to the cart drawer, then more shoppers will complete a purchase because wallet users can pay without filling in the checkout form.
- Primary metric: Revenue per visitor
- Guardrail: Average order value
- Guardrail: Cart drawer to checkout click-through
- Guardrail: Order refund or cancellation rate
- Who should test it: Stores with a slide-out cart and a large share of mobile or repeat shoppers who use digital wallets. It may do little if most of your customers pay by card or invoice, or if express pay already sits on the product page.
