I don't know if they have the new 40th anniversary pins or not, yet, but I'm told they're going to be $15.
Last time we were there (June 15), they had the 40th anniversary wine glasses. Before we asked how much they'd be, we both told each other our price estimate. My wife guessed the amount exactly (a much higher price than I thought they'd be). Coincidentally, she met Bob Barker that same night. Hmmm, perhaps it wasn't such a coincidence . . .
The regular pin is $10 the 40th anniversary pin is $15. When I bought my ears they were $15, but that is when they first came out, they may have gone up in price over the last year and a half. I don't know the prices of this stuff, but last time I was there they also had a 40th anniversary travel coffee thermal mug and men and women's polo shirts with the 40th anniversary logo.
