Why the hell do they put limits on coupons?

If this makes sense to anybody, please let me know because it makes absolutely no sense to me. Finding a coupon for 10, 20, 40 percent off at departments stores is always a good thing. Saving money always good. But then as you read the coupon, below the percentage off and days the coupon is good, is a nice little paragraph is teeny letters of everything the coupon will NOT work on. Expensive brands, okay makes a little sense that they would be excluded, but excluding the entire appliance department? Or saying that you only get 10% of in that department instead of the 20% off. What the hell sense does that make? Why is the percentage off less in stuff like appliances and bedding? Seems like a whole hell of a lot of confusion to me.

You would thing the employees would go insane eventually trying to keep up. You might say they have computers that keep track, but hell, if I walked through Penny's and saw several smoking check outs, I wouldn't be surprised. They get so much stuffed into them and then taken out everyday.

And then there's the coupon that says '$10 off, it's our gift to you!' then precedes to have the little exclusions paragraph. What the hell sense does that make? We are giving you this gift of 10 dollars off but we are going to limit you on what you can use it on. Doesn't seem like much a gift to me. You just end up wandering aimlessly through the store, getting pissed because everything you are willing to buy doesn't accept the coupon.

Another thing I wonder is why grocery coupons sometimes give a certain size of container the coupon is good for. And generally, it is the huge size you don't want. It doesn't seem to me that you are saving money by using a coupon for a 24 oz tub of cottage cheese if half of it ends up going bad before you can use it. I don't see the savings there cuz you're throwing away half of it. And the large cereal boxes. .okay, tip manufacturing guys. If it's bigger than a standard cabinet, DON'T MAKE IT. Who wants a box that won't fit into the cabinet so you either have to leave it on the counter or leave the cabinet door half open all the time?
