Kohl's BF sales on 11/25 B&M,

DON'T STAND IN THE COLD, use your brain not your feet.

The Kohl's ad team will be putting out the signs for the Black Friday deals between about 6pm and 12am and the store is open till 12am. The cashiers will fix the price to the BF price if there is a sign out and they don't usually check, just take your word for it.
The manager at my local Kohl's told the cashiers to honor the BF prices if anyone asks/tells about the sign last year and I made out like a bandit, minus the eventual jail.

IF ALL ELSE FAILS: If the sign is up they have to honor the price, so wait around untill near 12am when all the ads must be out so you get the price.
