We needed to establish a reward program in our store, but default Magento doesn't allow it, so we decided to implement the Amasty Reward Points extension. 

Now, customers receive points as a reward when they make a purchase on our website. Additionally, they are informed on the product page that the product is part of a rewards program:

The extension works very good and is user-friendly. It enables us to easily create rules for our reward program. We've been using the extension for 3 years, and this program has attracted a greater number of customers.
