If you join ebates and go through their website, they will send you another
3% cash back!
If you are not already a member, here's the link to get started:
http://www.ebates.com/refer-a-friend/0809promo.htm?referrerid=aq32K406U7yoVBJ%2FFa4XGg%3D%3D Both you and I will earn $10 cash back.

Once you are a member, you can sign up your friends and earn bonuses. Once a quarter, you will be mailed a check with your rebate amounts based on what you spent on websites accessed through Ebates. Many websites pay search engines based on what you purchase. Ebates is just giving a portion of that back to you! I never shop online until I see if they do a cash back through ebates or not. If your desired website is listed, just click on it and your tracking ticket will keep track of what you bought and credit your ebates account. I'm skeptical by nature, but it really works! Give it a try when you shop online!
There are several websites online that will give you cash back for online purchases.
bigcrumbs.com is another one that I use frequently, depending on which site has a higher cash back amount. The thing I like about Big Crumbs is that their payouts are monthly, and so I get my money deposited into my Paypal account which i then transfer directly into my bank account. With Ebates they only send out checks 4 times a year, and you have to have accrued more than $5 of cash back (on purchases, refer-a-friend bonus money doesn't count) to get a check. And when you're only making sometimes 1-2% back it can take awhile to accrue enough money, which is a major disadvantage to Ebates, although I do use both websites.
I though am not going to solicit refer-a-friend bonuses on this website. But both websites are legitimate.
