Who says Twitter is filled with useless information? Okay, maybe it is. But there are quite a few Tweeters who send out alerts about deals and discounts. Here are 10 that I've found; let me know if you have any others.

Walmartdeals. Even if you're not interested in the pleat-front pants, it's worth following Walmart for the tech deals, like this Vizio TV for $537.

Bradsdeals. Brad Wilson runs one of the best deal sites I've found, and his Twitter feed highlights his latest finds. It's heavy on consumer products rather than tech stuff.

Buydeals. Updates from Buy.com, which is one of the best places on the Web to find good prices on gadgets.

Softwaredeals. I think this is also a Buy.com Twitter account; at least, that's where all the deals are from.

Dealsrightnow. Some apparel deals, but also a lot of tech stuff, like a Kodak digital camera for $100 from Staples.

CheapCentral. Recent tweets highlighted a $100 massage chair, a deal on binoculars and cool free iPhone apps.

FinancialBliss. Links to store-specific deals from chains such as Safeway, Walgreens, and Target.

Bargain_central. If you're a deal dork and want to be alerted when Domino's is giving out free pasta bread bowls, then this feed is for you.

Dealdigs. This feed offers an eclectic mix of apparel, electronics, flowers, video games, and restaurant coupons.

Me, of course. Follow me at hannahsteiman or Inc. at incmagazine; when I find good deals I send them out in both feeds.
