At my Publix, if a scanned item is not what is posted on the shelf, the item is free.
Exactly. Same at our local Publix. Ours also has numerous BOGO offerings of Of standard items like ice cream, chips, laundry detergent, etc. Standard prices may indeed be a bit higher than say, Wal-Mart, but Publix is superior just about every local grocery store here in NE Florida in available merchandise, staff, and cleanliness.
