Michael Jackson Whisky Connoisseur Glass

Sam's in in Chicago has them. If they don't offer them on their web site just send them an email. I'm sure they would be happy to sell them to you. Ditto Liquor Barn in Louisville/Lexington.

I bought mine on Ebay -- with S/H it was probably slightly less than average retail (which seems to be about $8 a glass, before sales tax). If you can find some on sale you can maybe do better.
You can't ALWAYS find some at auction, but frequently enough that you shouldn't have to drink from a tin cup very long. Just run a search for "Riedel bourbon".
