I've talked about Mr. Rebates before many times. This website, which has now been around ten years, allows you to save money online through thousands of stores simply by clicking through Mr. Rebates on the way to the online store. The rebates accumulate until you reach $10.00, and then you can request them through PayPal.
After you sign up, they'll even kick in $5.00 toward your first payout. Got friends? If they sign up through you, then whatever rebates they earn will trigger a 20% commission to you. Forever. (It doesn't reduce their rebate at all. This is a thank-you bonus from Mr. Rebates to you.)
For the Valentine's Day season, over 200 stores — like 1800Flowers.com, Ghirardelli Chocolates, ICE.com, ProFlowers, and many more — have increased rebates.
Finally, to celebrate Mr. Rebates' 10-year anniversary, they'll be giving away $10,000 to one lucky winner who visits Mr. Rebates while they're logged in. One entry for one visit per day through the end of February, 2012, so there's the opportunity for another 22 entries into this sweepstakes if you sign up today!

never heard of Mr. Rebates, but I will certainly be checking him out!
Happy b-day, Mr. Rebates! i will have to check this out since $10K is calling my name!
