I have this idea of offering sponsored slots on my CW items I still need to submit. Someone would claim that slot BEFORE the item is on-site and pay for the submission fee (less than what it would cost to buy the item afterwards), while I pay the 50% extra for the artist copy (mine). Is this allowed? I don't have much CSC, specially considering I'm a newb, but I'd really like to release some festive stuff in time for the next site event.

You should file a ticket about that one since it's a question about the rules :)

Thank you both so much, I will do it :)
