So pretty much what everyone does right before Christmas? Increase the price, so when they lower it, no one will realize that their "discounts" are actually when you'd be paying anyway. That's BS.
It is BS but sometimes you'll find some good deals. Example: They raise a $45 used game to $70 during the half off sale. You'd pay $35 for it during the sale, so really you'd still get $10 off what they were charging originally.
