The biggest, baddest, Black Friday ad of them all is no longer under wraps. That would be Walmart's.

You'll find the usual suspects, things like TVs, game systems and computers.

Grab a Compaq laptop for just $179 bucks, a 43-inch plasma for $378, and an xBox 360 bundle for $149.

But amid the bargain basement prices you'll see something new this year - an in-stock guarantee. That's s pretty much unheard of on this day of marketing mayhem.

It only applies to these three items: iPad 2, LG Blue-Ray player and Emerson 32-inch LCD TV.

If you're there when the store runs out of any of those things between 10pm and 11pm Thanksgiving night, you can get a rain check, and you'll be guaranteed to get it by Christmas at the Black Friday price.

Another highly anticipated ad is Best Buy, where this year, you can get your hands on a reservation ticket for certain items two hours before they go on sale. That may help you snag some pretty sweet savings like a 50-inch LED TV for $399, a Playstation 3 bundle for $199, and Blu-Ray movies for under nine bucks.

Like most things in life, the busiest shopping day is all about timing.
After years upon years of before-sunrise stampedes and duels over deals at 4am, now Black Friday is starting earlier than ever.

Retailers are encouraging you to dine-and-dash, since the bargain bonanza begins before your turkey will even have time to digest.

Walmart opens at eight thanksgiving night. That's two hours earlier than last year.

Sears and K-Mart will also open then.

Target starts the sales a little bit later. Doors there open at nine.

While this "skip the second helpings" approach may give some traditionalists heartburn, economic analysts say get used to it. Black Friday eve bargains aren't going anywhere.

On the bright side, it may be just the perfect excuse to get you out of having to help wash those Thanksgiving dishes.
