I've never thought about doing inventory for a toy show and having spreadsheets

I just rawdog the show when I go lol
"Will you take $15 for this?"
"What do I have it marked for?"
"$20."
"Sold."
"Do you have any Mythic Legions?"
"Uh.....maybe? Let's look"

I mean, I have a cash box and signs for Venmo, Paypal, and I take cards via Square. But I've never gone all fancy with it. I suddenly don't find what I'm doing to be a lot of work anymore

This makes sense though, other vendors ask each other "how'd you do?" and they usually have pretty definitive numbers. They ask me and I say "I dunno, I have to count it"...it all makes sense now.
I treat it very much like a yard sale, I suppose.
