My method is to save all my grocery ads. I start with page one and mark off the products as I email them using google. I have a list posted in my notepad in ABC order of the companies. I list the date I email them, the response I get and what I get when I receive the coupons in mail. I started at the first of this year and have received a ton of coupons. I'm in the process of starting again since it's been awhile since I have emailed companies. It's amazing how many products are out there.
