> So what if they are off by a few cents or dollars? Do you actually spend time to contest this?

I have. It's not a hassle. Especially if I'm already there for some other reason. I clip coupons for the same reason. A $5 discount is a $5 discount.

A $5 coupon is also worth ~100x more than a few cents so it's worth ~100x the hassle. For a sense of scale imagine if the topic of grocery coupons came up and someone started mentioning they still make sure to take the time to enter their $500 off member code at checkout because a $500 discount is $500 discount - well duh, it'd be free groceries at that point!
