I'm trying to look for a coupon to print out and bring with me to Barnes and Noble later, but I'm trying to look online for one, and all I'm finding are coupon codes for online purchases only! booo

So I'm trying to find some good reliable websites for looking for coupons! I regularly use retailmenot.com but they seem to focus on online purchases (which is great! but I'm going to a store today....)

What websites do you use?

PS......If you have any Barnes and Noble printable coupons, feel free to share!
