There are a couple store coupons that you can use at Publix if they are considered competitors, which they are in Florida.
The Save A Lot facebook promotion has been continued another month until 8/31/12. Go to Facebook and LIKE them to get a $5 off $25 coupon you can print one. The expiration date is rolling and it will expire 2 weeks after your print date.
There is also a $10 off $50 Sweetbay coupon you can print when you sign up for their newsletter. Not sure of the restrictions of printing, but I'm betting you can get extra with using a different email address on a different computer to print additional coupons.
