My K has a policy limiting 3 of the same Q's per transaction, not just dbl or tpl.

I found out the hard way on Sunday trying to use 4 Q's on 4 items and the cashier scrambled to find her lil placard (a simple txt printed 1/2 sheet of paper with lamination on it) stating such. She had to go 2 registers over to get it. I bit my tongue and said I will have to keep that in mind for next time. The Q was only for $.40 and I was getting 3 cheesy boxed potatoes for $.20 a box, and one for a $1. As I left I looked at main store entrance, where they had recalls and (tacky) handwritten poster 'managers' specials, and did not see any notification of coupon limits.
