What Is Cashback?

Cashback Explained: How Cashback Works. Cashback means getting money back after making a purchase.

For example:

If you buy something for £100 and the cashback offer is 10%, you receive £10 back.

• Banking apps

• Retail loyalty programs

This is one of the easiest ways to save money without changing your shopping habits.

How Does Cashback Work?

4. The retailer pays commission.

5. Part of that commission is shared with you.

This process usually takes days or weeks to track.
