I guess I am just annoyed at recent convention, where I was the 2nd person in line after waiting 1 hr.
I just happened to reach a booth some older gentleman who had a TON of great keys for good prices (like 5-10 dollars).... I was the earliest attendee at his booth but there was the dealer from 3 booths away who was already there with a HUGE stack... he essentially swooped in and bought up about 80 % of the keys, asked for a dealer discount on top of it. I ended up buying two comics and left the rest because I owned them.
I was just annoyed when I got to that dealer's booth 15 mins later, I saw him resticker everything and put the exact comics on his wall at 40 -90 dollar markups.
