The prices at Target are marked down according to their computer system. When I lived within 25 miles of 6 different Targets and was heavily into shopping, I would haunt the various Target deal threads on coupon boards. I was on the west coast at the time, and I noticed that things would get marked down on the east coast a couple weeks sooner than the west coast. The mark downs go according to this: 25% off, then 50%, 60% - 75%, then finally 90% off, before the item goes to salvage. This was great as I could scout out which Targets near me had the items, what were their current prices, and which ones I had to head to the first thing when they opened on mark down day. Different departments mark down on different days each week. There is a list online somewhere. 3 - 4 of the stores might be marked down to the same price, i.e. 50% off, in the same week, while the other ones lagged by a week or two, even though they were all within the same vicinity.
I just had to keep showing up each week and scanning the items until they got marked down to the right price. The scanner is your best friend at Target. Never rely on the sticker price for markdowns. By the time they've been sticker priced, an employee will have scarfed it up first.
I got a $79 toaster oven for $9.99. That was one of my best deals. I need a new one soon as it is finally conking out after several great years of use. Too bad I'm not close enough now to a Target, to make the hunt there worthwhile.
