If you visit the Southern Savers site, there is a link at the top that will tell you the coupon schedules for the year. It will tell you in advance what coupons will be in each insert. Check it out.
Also, please note that on HOLIDAY WEEKENDS, there are no coupons in your local papers. I also know that locally, you can get a Sunday paper at CVS and Walgreens for $1.00 and $.99 respectively, so if you want to buy additional coupons, you can do it there.
My friend Dee'Anna told me that she was able to buy just the coupons later in the week at CVS. She said she paid $.50 for them.
