Some people can never have enough tin foil.
I guess they pay full price for every too because I assume even those little grocery store key chains cards are a no no.
I am sure that those grocery chains use my purchases against me,
I like to shop from store to store to get the best buys, and with those cards they can figure out that a few customers buy lots of sales items.
But I dont put on a tin foil hat over it. .
