Don't succumb to that post-turkey nap just yet — you can already shop incredible sales at Amazon, Walmart and other big stores.

Since Black Friday isn’t really a single day, don’t feel compelled to shop on that day, says Maurie Backman, a personal finance writer with Motley Fool Money. She says you’ll be able to find similar prices throughout the holiday season and that you shouldn't be fooled by the discount retailers say they’re offering.
