Ok so after calling 3 different Publix's-they only accept 2 coupons per item-1 Manufacturer & 1 Store (either Publix or Competitor).

So for the Sudafed deal-
You can use the $5 off coupon & the $3 off Walgreens (since the Publix one is only $2) & you will get the medicine for $1 so if you need it then that is a great deal!

Thanks Heather for helping me clarify that!
