About Rebuy
Rebuy's packages cover Smart Cart, merchandising widgets, checkout and post-purchase, search and A/B testing. Pricing starts at $25/month and scales with orders and with the packages you choose.
It's a good app. Merchants usually compare alternatives for one of these reasons:
- You don't need AI search or advanced flows, just a strong cart and offers.
- You want a simple monthly price that's easy to predict.
- You want to set it up yourself in an afternoon.

How to choose
- Count your orders: order-based plans grow with traffic, revenue-based plans grow with results.
- Test on mobile: most carts are opened on a phone, check the checkout button is always visible.
- Check compatibility with your bundle, subscription and gift apps, or use one app for all three.
- Measure average order value and conversion for two weeks before and after the switch.
