It depends on the store and their policies. Some stores wont give you money back. So if you have a 2.00 off coupon and the item is on sale for 1.89 you wont get .11 back. Some stores will. We have gotten cashback a couple times but usually we wind up just dropping our bill to a very low number and be happy about it. And I agree 75 jars of mustard is insane. Perishable stuff we buy only a few at a time. No sense in having 100 jars of spaghetti sauce if 75 will go bad. But TP,paper towels......If we can get them for pennies or free we get a bunch and just store it in the garage.
