It looks like these update every month! I was able to find many of the products at Giant Eagle, where they doubled the coupons under $1.00 for even more savings!
There are a lot of other couponing websites and blogs out there, including The Couponing Kellys and Proverbs 31 Chic and the many great resources that they link to!
Check out coupons.com (there's an ad at lower right) for printable coupons. You have the best selection at the beginning of the month!
