Here's a great Kohl's trick. Shop for everything you want the Wednesday night before Thanksgiving (they won't have the door busters out so if your interested in them it won't work). Well anyway, put all of the stuff on hold, they'll hold it for 24 hours (and Thursday doesn't count because they are not open). So come BF as soon as the store opens I walk right to the back and go to customer service and get my stuff (they put it in clear bag so you don't even need to worry about getting a cart). And walk right up to the registers, there's NO line. I'm in and out of Kohl's 5 minutes tops - with my Kohl's cash!!
And yes according to the Kohl's manager, if you are in the store Wednesday night and they've already put out the sign for the black Friday sale, they will honor the price - but you'll have to tell them because the registers are not programed for the discounts yet.
