Back in November I did a post on Ebates vs. Mr. Rebates and I think that it is time to bring that back up! I use both sites in my sale and deal posts quite a bit. This time I will also add Cashbaq and UPromise as I will use those sites in my deals occasionally as well.
All four of these sites offer rebates if you shop through them (use their link when you go to the online store). This is paid for with the affiliate income they earn when you shop. They all four also post coupons on their sites, which can be combined with the rebate.
Ebates is probably the most common rebate site. You will get $5 when you sign up. You have to have $10 to request a check and THIS IS IMPORTANT!!! At least $5 of that money has to be from your own personal rebates. If you have $10 in referral income then they will not send you a check! As far as referrals go, you will get $5 if somebody signs up when you refer them and then they purchase something through Ebates. If they sign up and do not purchase anything then you will not get anything.
This site is a little less known, but it is my favorite. I find that the rebates are the highest for this site about 75% of the time. You have to have $10 in your account to request a check, but it can be any sort of income (referral, your own, or contest). They do hold contests occasionally. Their latest one was in March and the winners got $100. A reader of this blog just emailed me to let me know that she won! When you sign up you will get $5. As far as referrals go, you will get 20% of the value of the rebates (not sign up or contests) your referrals get. That means if your referral gets $1 for a rebate you will get $0.20. The referral program for Ebates is better for people who want quick money and for the people who sign up and only use it once, but the 20% program with Mr. Rebates earns more with the people who continue to use their program.
UPromise is a great site if you have children, student loans, or plan on going to college in the future. It works the same way as the other two, but instead of your money going to you via check it is kept in an account that can be used for college. You can even transfer the money to an interest bearing tax free account!
