Drops
A drop is a piece that is made once enough people back it. You back one by holding credits against it — no card is taken then. If it reaches its minimum you are contacted to pay; if it does not, every credit is returned.
Voting is free. A vote shows other shoppers how much a drop is wanted, and every vote has a chance of dropping design credits or extra wheel spins. It is not backing: votes do not count toward the minimum — only credits held against a drop do.
No drops are running here at the moment. New ones open regularly.
