*This might not really work sometime (if the player been scam like this before)

1. trade with any body, first put some rich stuff, if your poor, then put the most richest stuff u have.

2. if u put rich, the other player will put rich too (of course), then put alot of bargain stuff, till the trading window is full.

3. U need to do this quick, as u put many stuff, the player will scroo down, and then u quickly delet the rich stuff u put and quickly comfirm.

4. the player if is careless will not know and comfirm too, but if he/she check and find u delet, too bad, this trick is end up.
