> If I buy a lot of Scott toilet tissue, I'm happy to get a discount on Scott toilet tissue.

Don't expect discounts on what you buy often. They know they have you hooked on those already and they'll drive up the price on those items (for you) the minute they can. They'll give discounts on brands you don't buy to entice you to switch (if those other brands pay them enough to do it). These surveillance pricing systems are not for your benefit. They aren't there to save you money. They only exist to take more of your money away from you.
