It's not that bad of an idea, really. Most of us do have a fair bit of "junk" around, but people are willing to buy it. I sold a Russian hockey jersey I bought for $8, I paid 50c for it a couple years ago at Salvation Army. This looks like it might be a viable, well, maybe not "career" for me, but certainly will give me some pocket money. One convenient thing, too, I started my own paypal account independent of my mother's, so I don't have to go through convincing my mom to let me use her paypal account/bank account when I wanna buy stuff online. What I'm figuring is, through ebay sales, I can make most of my online purchases self sufficient, if you will. I can sell random junk on ebay, and have it convert into online money.
One thing convenient for me, too, is it'll convert "real life" money into "online" money, which is good for me. Like the jersey I sold, it was $12 for shipping, so I spent $12 real life dollars, but I have $20 in the paypal account. Once I get a bank account, that's all sorta null and void, but in the mean time, the shipping comes out of my pocket, but it converts pocket money I generally spend unwisely into "online" money, which I can spend much better.
So, sell your stuff on ebay. Not a bad way to make a little cash. Maybe I can eventually make a job out of it and save up for a house or two (I want houses in Maine and somewhere overseas, the houses in Maine I want are 20-50K, so paying my mortgage wouldn't be any worse than a car payment.)
