If you didn't know you needed it, you don't need it.
As Thoreson puts it, if you didn't know you needed something, then you really don't. Black Friday preys on the discount-obsessed and sleep-deprived among us, and stores have myriad ways of laying on the pressure to hook you with impulse buys. Your best strategy is to stick to the game plan and be methodical. Have your list and no matter how tempting, ignore all other offers. "You don't need that $3.99 Dustbuster, or whatever they're offering, that badly," Thoreson says. You likely don't need an 840-count pack of baby wipes either.
