Within my family, I have become known as a coupon specialist. I typically save 40% of my grocery shopping at Kroger.
While I don’t often make purchases on line, I don’t think much about on-line coupons. I have written in the past about sites that have coupon codes for various merchants.
RetailMeNot has a list of 70K codes. It also has a search engine. That way you can search for particular products or merchants for codes.
