Costco just marked down their Kirkland brand spiral hams on Wednesday to .97c per lb. It's a great deal if you're interested. I was there today and they still had plenty.
Was it the kind in red tinfoil? I was told by an employee at my local Costco that they were marked down because of mid February sell by dates. I wonder if what you saw was the same? I'll either use mine by then or throw it in the freezer.
