Well, the deed is done. Did a Buy It Now for $3/pin. I did see another set for only $2/pin, but it was twice as many pins and an additional $40. I tried not to go overboard and figured $3/pin is good enough for me.
Thanks for the help. Since the seller is doing this "grab bag" style, I have no idea what pins I'll be getting. That's kinda fun. I hope there aren't too many we like - we plan to use these to trade!
