They're a grocery chain based out of Rochester NY. They used to do the free abx, but stopped it when they started doing this. Probably started this around October or so, but I don't exactly recall.
They could probably operate the pharmacy as a loss leader since their grocery dept and precooked meals are so successful, so the little bit of cost for the atorvastatin is insignificant. The pharmacy is definitely not a loss leader for them overall though, to my knowledge all of their stores fill 500+ and some are even 1000+. They have definitely taken a lot of scripts from the other chains with this promo.
