Promoting express delivery more clearly at checkout, while making Stripe the preferred payment method, raised revenue per user by 16.01% and average order value by 4.36%. Sculpt Digital ran this test for a UK WooCommerce store, and it was published as a Convert.com case study. Both changes shipped together, so the result can't be pinned on either one.

## Result

**+16.01% revenue**

- Revenue per user: +16.01%.
- Average order value: £60.46 to £63.10, up 4.36%.
- Express delivery uptake: 2.15% to 4.87% of buyers, more than double.
- A metric labelled revenue conversion rate rose from 43.50% to 48.36% (+11.15%), as reported.

## Control

Shoppers often missed the express delivery option and fell back on free shipping. PayPal was the default payment method.

## Variant

Express delivery was promoted so it was easy to see and pick. Stripe became the preferred payment option, since it costs the store less to process than PayPal.

## Why it likely won (our reading)

- Session recordings showed people didn't notice the faster option, so simply making it visible let those who wanted speed pay for it.
- Express delivery adds a fee to each order that picks it, which lifts order value directly.
- Stripe's lower fees help margin, but they don't change what shoppers pay, so most of the order value lift likely came from delivery.
- Changing the default payment method may also suit shoppers who prefer to pay by card.

## Caveats

Delivery and payment changes were tested together, and the results table labels the arms pre-test and post-test, which is unusual for a split test. The test ran 35 days on all visitors; sample size was not shared.

## How to run this test

- Hypothesis: If we make express delivery a visible, one-click option at checkout, then average order value will rise because shoppers who want faster delivery will notice it and choose it.
- Primary metric: Revenue per user
- Guardrail: Checkout conversion rate
- Guardrail: Express delivery uptake
- Guardrail: Payment errors or abandoned payments
- Who should test it: Stores that offer paid fast delivery next to free shipping and see low uptake. It probably won't help if few customers care about speed or express margins are thin.
