Today is the last day to earn cash rebates by shopping and buying through Microsoft's newish search engine Bing. The cashback deals are, frankly, insane. 15% back at Walmart. 20%t back at Dell. 35% back at T-mobile and AT&T.

These rebates are unheard of. Bing Cashback is going to give eBates, Cashbaq and Extrabux a run for their money. More rebate offers than end today:

5% back at Buy.com
5-10% back at Best Buy
8% back at Home Depot
8-12.5% back at TigerDirect.com
10% back at Macys, eBay, The Gap, Kohls, Old Navy, Banana Republic
13% back at Sears
14% back at Barnes & Noble
20% back at HP, Sephora, Endless Shoes, Dell, Shoebuy, Drugstore.com, Lenovo
25% back at Footlocker and Eastbay
30% back at eBags

But there is a catch. You have to wait at least 60 days until after your purchase to get the moolah. The waiting period varies by store and you have to request the cash, so you'll need to set a reminder in your calender. You can get paid by check, direct deposit, or paypal. Minimum payout is $5.
