Description

Payback is an e-commerce site where people can buy and sell products. Users can communicate with each other using build-in messenger. To understand how reliable a seller is, users can view all reviews about that particular seller (a review can be left only after the product has been purchased).
Initially, access to the site is read-only. Users must authenticate in order to perform any actions, such as buying or selling products.

Disclaimer: Payback is a pet project. All users and products presented on the site are not real, their photos, descriptions, etc. are obtained from public APIs.
The payment system is working in test mode.

Buying products

The payment system works in test mode, so the real payment won't be made. You can buy a product just for proof of concept.

To buy a product:

1. Sign in
2. Go to the page of the product that you want to buy. Let's say it's product #35
   
3. Click "Buy" and follow the instructions provided above the "Buy" button to make a test payment

If everything goes well, you will be prompted to leave a review. From now on, this product is sold. The balance of the user who put this product up for sale will be increased by the price of the product minus service charges.
