Replacing payment logos in the cart drawer with a PayPal Express button raised conversion rate by 37.33% for automotive parts brand Aeromotive. Blend Commerce ran this A/B test in the brand's Rebuy Smart Cart. Average order value rose 35.60% and revenue per user rose 75.48%.

## Result

**+37.33% conversion**

- Conversion rate: +37.33%.
- Average order value: +35.60%, a large jump for a payment button change.
- Average purchase revenue per user: +75.48%, combining the conversion and order value gains.

## Control

The Rebuy Smart Cart drawer showed Affirm and credit card logos.

## Variant

The logos were replaced with a working PayPal Express checkout button.

## Why it likely won (our reading)

- About 26% of the brand's revenue already came through express checkout, so many buyers wanted a faster way to pay.
- A clickable button does more than a logo: it lets shoppers act on the trust signal right away.
- PayPal may feel safer for large orders, which could explain part of the order value rise. This is our guess; the source does not explain it.

## Caveats

Sample size, test length and confidence level were not shared. Results are reported by the agency, and the order value jump is large enough to be worth retesting.

## How to run this test

- Hypothesis: If we replace static payment logos in the cart drawer with a PayPal Express button, then more shoppers will buy because they can pay with a trusted method in one click.
- Primary metric: Conversion rate
- Guardrail: Average order value
- Guardrail: Use of buy-now-pay-later options such as Affirm
- Guardrail: Revenue per user
- Who should test it: Stores where a meaningful share of revenue goes through PayPal or other express checkouts, including high-ticket stores. Be careful if financing options like Affirm drive big orders; removing their logo could hurt those buyers.
