Purely anecdotal Sam's Club observation over the last 6 weeks...
We eat a lot of chicken. We used to buy the 6 or 10 lb bags of boneless/skinless breasts from Sam's. But they go kinda weird and huge so we switched to the bags of tenderloins (better portion size for me an the wife). The point is, in that freezer section at Sam's used to ALWAYS have at least one (usually two) full pallet/section of the breasts, another full pallet section of the tenderloins, another of wings. A couple of weeks ago, no tenderloins and no empty section, it was filled with glazed party wings. Last week, no breasts, no tenderloins, no regular wings, just two sections of the glazed party wings. Not sure what the Walmart situation is vs Sam's.,
Also during that period, dropped into WinnDixie because they had BOGO on bags of tenderloins... 3 lb bag was $22 for the BOGO "deal."
