If your looking for the best deals at Publix or Winn-Dixie this week, check out http://www.fiddledeedeemom.com, Sarah has all the printable and non-printable coupon matchups.
For a preview of what will be on sale at CVS and Walgreens in the coming week check out Andrea @ Mommy Snacks. She has an advance copy of the sales ad along with coupon matchups.
Also, if you see an item you want to stock up on, don't forget you can order extra coupons from The Coupon Clippers. You can search by brand and they understand that coupons are time sensitive so you will get your coupons quickly.
Lastly, sign up with The Coupon Mom to search for coupon matchups by state. She lists matchups by date and insert name, such as Red Plum, Smartsource or P&G and will also tell you where to find additional printable coupons. I have switched to Coupon Mom's method of organization and it has saved me tons of time because I'm not clipping and organizing coupons that I don't use.
