GREENSBORO, N.C. - 4 a.m. wake up call? Enough already. Sleep in. Then when you wake up, start checking eBay for the door busters you wanted. Lots of crazy folks will hit the stores for a big deal and then hope to turn a quick profit by posting their purchases on eBay.

Also know that waiting can actually score you better deals. The folks at Rather-Be -Shopping have tracked prices for years. They've found the best time to buy what you really want.

Computers and Tools: December 13
Clothes and Kitchen Stuff: December 15

And If you really want one of those great deals on a tv, The Deal Guy Matt Granite says wait until after Christmas. You might get a higher quality product on sale around the time of the superbowl. He says the ones sold on Black Friday are often Grade B brands and have quality issues.
