If you have not signed up for a Bing.com account yet, this is a good time to get it done. There are many cashback deals from BING.com
HOW IT WORKS – Using the Bing.com search engine search for the item or store you want. If you put in AT+T or T-Mobile, you will see 35% CashBack. Click that link and follow the instructions.
After your purchase is complete you need to wait, sometimes it takes a day or two, and other times just a few minutes for the cashback to show up in your bing account. Then you need to wiat 60 days before the cashback is released. You can have them send a check, or put the money into your PayPal account.
I choose Paypal.
