if you need money, you can do it via an unorthodox way, it is risky nonetheless.
1) get someone who is willing to buy a small bag for a cheaper then vendor price, or at the same price, if they are on their way to go get one.
2) Tell them to have slots empty to the amount of bags they will buy.
3) Have them give you money via trade, and tell em that you will get in trouble if you run away (which is true) via complaint. Afaik...
4) give them the bag(s)
OR
1) Use a different way.
or
Sell a note on the auction to have someone meet you so you can give them the bag, (They buy the note for that price, show it to you, and you give them the bag.) You will find out who bought your note, and so will they. (By paying attention to updates.) That's something that I just came up with... again risky for the customer.
