When you post multiple trades, all trade is supposed to be sent separately in order for it to count as individual trades. Creating/posting multiple trades and then sending as one is construed as padding your feedback/trade count. Should this occur, all the trades needs to be combined into one trade. Contact a mod if you need assistance in editing a trade.

Trading in this fashion is consider Feedback Fraud, which results in an automatic 7 day suspension from the site as well as losing all the feedbacks/trades that were done in the groups of trades.
