Have you ever wrote/called/emailed a company to complain or compliment their product? Have you ever gotten any coupons/freebies from it? I have not really tried this method of obtaining coupons, but it would probably be really benefical in getting my grocery budget down!
You have to check out this guys website: The $39 Project. I am dying of laughter at some of his letters to companies. Plus, it could help you figure out who to write and who to not bother.
Let me know what you think!
