I am a bargain shopper. I use the ads to look for sales, and then I use coupon websites to save even more. My favorite part is when I check out and the cashier looks at the bottom of the receipt and tells me how much I saved. I feel like a really great shopper. Wouldn’t it be great if you got a receipt that printed out your savings every time you checked out books or used other materials at the library? The computers won’t do that, but there is a way to figure out your savings.
