I always buy things that are on sale. I mean if I can save money, I will do anything. That was why I was so fascinated with Saivian. I thought it was really weird at the beginning. What benefit does this company get by offering these customers 20% cash back? I guess it comes from the membership fee. But then I've been able to use the cash back to pay off the membership fee. I get a few hundreds of dollars every pay period through the program. I am happy with it.
