Wondering what exactly are the rules for stacking coupons at SOF. Do you have to tell the cashier when you go through that you want to stack - or do you just give them to her? Not sure why - but I am a little nervous about tying to stack.
I have some tear pad coupons - that are different values for the same products and not manufacturer coupons that I would like to stack. Just want to make sure I do it right!
