trade center is basically for buy/sell/exchange among members.
simple and strict rule for this section is: no discussion about a product. if some1 posts a product, prospective buyers should contact through the contact info provided by the buyer or by private message.
if someone's product/item is sold out, then reply in this topic: notification for sold out items confirming that the product/item has been sold out. mention the link to the topic too, so the moderator can rename that indicating that it has been sold out. you can also mention details of the deal like buyer, price etc.
update[12.4.08]: feedback section has been opened for light discussion. but be warned it will be heavily moderated: posts deemed malicious will be deleted without notice.
added[23.11.08]: advertise your products, buy, sell and exchange in BanglaGamer shop at your own risk. BanglaGamer.com is not responsible for your transaction. it is advised that you surf and ask around about any seller/buyer's credibility.
update[12.4.08]: a minimum of 25 posts is required in order to open a new thread in the shop for selling/buying purpose.
