Hi Everyone
I just attended my first Cardshow event it was really fun.
I wanna share an experience and get some input:

I was trying to sell two TR cards to a vendor which he already had listed at $55 on his desk
He looked at my cards and looked up the price on his phone and told me very politely that they were good and he could pay me $20 cash for each.

My question is:
Is this the average experience? I'm guessing it costs a lot to attend a cardshow. Or was it a lowball offer/nice try from the vendor?

He did seem genuine and it's cheap cards. It just weirds me out that as soon as it is in that glass case it's $55
