If you were going to be buying it anyway why does it even matter what the price is? Why can't they just list it at the coupon price for everyone?
I would normally get those at the store I normally buy that kind of thing when I'm there to get other things. E.g., most groceries come from the big Walmart Supercenter near my house. If I get a flyer in the mail from the Safeway that is on the other side of town, and see they have a good sale price on one of those things, I might stop by that Safeway when I'm in that part of town on other business and get it.
