Hey Joe!
I'm Dan, I occasionally volunteer for the convention and I've attended
for the last few years.
We're trying a new consignment system this year, check out the news
post here (link to website and FAQ):
https://vcfed.org/2024/07/22/vcf-west-new-consignment-system/
All items for sale are placed in a designated room and/or hallway space,
and people are generally allowed to poke, prod, pick up and look at
items.
During consignment setup, the convention usually asks for seller
contact details so potential buyers can contact with questions.
In the past I've seen sellers plug in computer to demo that they work,
but that's been rare.
Never seen any potential buyers power on or open systems, and I can't
say I've heard of anything getting broken.
Hope that helps!
- Dan
