Our Kroger's has started carrying cryo'd flats "occasionally." One week they have them then they disappear for two, then they're back. Last time I saw them though, they were $3.49/lb
Our Kroger only carries flats, and being able to get whole packers makes the trip to Walmart or Sam's bearable. Got a choice packer yesterday for $1.98 at Sams. A couple of mom and pop meat markets 'round here might carry 'em, but they're too pricey.
