mace (retailer) promotions

Is an overcharging policy in operation??

I just want other peoples opinions, my local mace store have promotions, e.g. two for a reduced price or whatever, but these goods are charged at full regular rate at check out. Most people don't complain so i guess it goes smoothly and profitably.

To my shock this morning I complained, having being overcharged on at least one item each weekend for three weeks now. I bought surf breeze 1.1 kg, marked 2.69 on shelf, but 3.80 at till, complained after going back and checking, received a refund for the difference, but , to my amazement, that was it, no changes were made to till system, so the next person who picks up a box will be charged 3.80.

In a time when many people don't check receipts for small items, it is these little, ongoing rip offs that frustrate me. So please let me know if this policy is being practiced elsewhere, or just here.
