Why do most people not use cashback website? Is there what to lose?

Answers

Jennifer

people either dont know about them, forget to log into those sites to get the benefits OR choose to get some other deal. For example, I can log in to my preferred airline and earn airline miles from my purchase.

People make their own choices about how they want to live their lives.

You do not get very much cashback for all the information they want to mine about you.
