This past weekend I had a table in Connecticon's Artist Colony. I was selling $5 custom I.D. badges along with buttons and other junk. I took orders for them by having people fill out the bottom (which has a list of things like Name, Favorite Character/Pairing, etc.), I would take a picture of them, and work accordingly. Most people paid up front while others paid when they came to pick up the badge and, by my own fault, I didn't keep track of who paid and who didn't.
Somewhere in the craziness of the weekend and the long queue for the badges, I missed reconnecting with three customers and left the weekend with their finished orders. If they paid for them, which I assume they did, I'd like to be able to refund them or mail the badges to them (or both). I didn't get real names or any way to contact them, though. I also don't know what to do with their orders now...I can't reuse the materials and I can't resell them or anything.
So far I've put up a post on the convention forums hoping that there's a slim chance they read them, but the forums themselves seem kind of bare so I don't think that will go very far. I'm just really really trying to avoid any possible chance that people think I purposely took their money and didn't give them their order. :/
