NEW YORK (TheStreet) --  You can get a great deal on Black Friday but you have to know where to go.

Clamoring for consumer dollars from holiday shoppers, retailers have already released their special deals in Black Friday circulars, with some like Walmart (WMT) - Get Report , Sears' (SHLD) Kmart and Amazon (AMZN) - Get Report kicking off sales well before next Friday, in a bid to one-up each other. Figuring out which stores give the best discounts will be the key to a successful day of shopping. And the best deals may not be where you think, according to personal finance website WalletHub.
