I don't know if this is in all of the eastern US states that they service but the ShopRites in NJ and NY have choice center cut rib roasts and grass fed ribeyes for $4.99 from 18-24 December, limit 1 of each......
I spotted the ad while visiting a son in NJ yesterday. We don't have ShopRites in Central NY but I have to be 6 minutes from one in Albany on Thursday so I'll be picking some up. Another son in Peekskill just bought an MES 40 and is likely stocking up too.
According to their website they have stores in NY, NJ, CT, DE, MD and PA.
