I find the stuff on the bourse floor of shows terribly overpriced, and that's even when the note matches the assigned grade.
It's funny you should say that R_P. I haven't been to the Torex before, but my impression at the Montreal show has been the complete opposite.
I realize you probably collect a much higher caliber note than I do [I don't have any unique $4 chartered notes, that's for sure!!]. But at Nuphilex, I'm always finding notes at a discount that I've been outbid on time and time again at [online] auctions.
As far as grading goes, of course some notes are over-graded, but I find the bourse floor is the only place I have to hunt for those so-elusive super-gem notes. And lots of notes available on the floor you just don't find anywhere else at all.
Picked up this beauty at this season's show:
