High cost flipping

Everyone know that the more money you put into something the more profit right? but it's also more money you are risking ,if something goes wrong. In these market is promodial saronite and battered hilt. I often like to flip these from the trade to the auction house, because some people think i just want to get rid of this and get some gold. So they sell it 20% cheaper then the auction house this is when you snatch that item from trade and post it up on the auction house, there easily 20% of that item in profit isn't that nice. But as i said not many people have the money to flipp these items, if you have you should absolutely do it.
