How to offer product samples with credit toward the full-size item in Wix Stores
Updated 2026-10-19
Why samples with credit
Samples lower the risk of a first purchase: flooring, fabric, paint, tea, cosmetics. But if the sample cost is simply lost, fewer people take the next step. Crediting the sample toward the full-size product turns it into a down payment.
Set it up
- Add Karelia Sample Credit from the Wix App Market. It works with Wix Stores.
- Link the sample product to the matching full-size product. A sample button appears on the product page.
- Choose the credit percentage, how many units a code covers and how long it is valid.

What the buyer gets
After a qualifying paid sample order, the buyer gets a one-use code that only works on the matching full-size product. The private dashboard shows source orders, credits and redemptions, and lets you retry credit processing.
After a cancelled or refunded sample order, the credit is put up for revocation review.
FAQ
Can the code be used on any product?
No. Each code is tied to the full-size product that matches the sample, and it can be used once.
Is it free?
Yes, Sample Credit is free on the Wix App Market.
