I think the easiest way to make profit or revenue is trading sites such as barter junkies. I have successfully traded stuff of low value and sometimes tripled to making as much as 10 times the value of what I started with. The most important thing to remember is to have patience. If you trade something to fast you could lose your chance to re trading it for something of more value. If I really had more time I can make up to at least a 1000 a week on a good week. That's just me. Im sure it is possible to make tens of thousands of dollars a week. That's my little intro on how i'm able to make extra revenue. Thanks, Seth
