Hi, Papa / Bodacious,
I did a little searching but could not find any current reports on retail brisket prices. I haven't bought on in a few weeks but I know I didn't pay that much. Mr. Brisket, an online retailer is charging about the same as you paid.
I did learn that brisket sales spike at Easter, Passover, Memorial Day (big one) and July 4th. My guess would be that Easter and Passover have driven the price up.
