Publix Penny item

I ran in this morning to MF Publix  to get the penny item for today- Publix sugar- wasn't going to miss that one- and I used self- checkout and just asked as usual for the penny item discount. No problems. BUT then, went in with my mom this afternoon and the checker said they now required the coupon from the Wed Tennessean. What? They've never required the coupon before. She said it was to go along with the Tennessean promotion they have going right now- Sunday paper is $1.19 and weekdays are... .50? I'm not totally sure. But if you have to buy a Wed paper, makes the penny item more than a penny. Not sure what other Publix stores are doing on this one but here's a heads up for MF shoppers.
