Well, for me it is.
Legs of lamb at the local IGA were a tiny $6/kg yesterday. They had stacks of meat. I bought some cheap T-bones and Y-bones, but not a leg of lamb, I couldn't carry it and was going for a bit of a drive before going home.
Today I go back and the shop's been hammered. Hardly anything left. No legs of lamb. Arrgh.
They're full price tomorrow.
