Plan to create Bid System

Bid System is a buying & selling place. For the seller, you can set whatever prize for the items. If the items are too expensive no body will bid it or if you set reasonable prize, people will bid it until the higher prize. Don’t need to worry about set the prize is too cheap. For the buyer, can bid until the maximum you can pay.

It has some rules, one account the maximum is 2 slots for you to sell and the maximum items appeal 1 month time only. If the buyer spams the bid, the account gets banned permanently.

Hope you can understand the explanation.
