anyone who says they are making a ton/living is either:
a) lying
b) living with their parents and just buys little things
c) no clue what stuff goes for in the real world, so a ton would be maybe a couple hundred
I think you're wrong to be honest.
Depends on the site. I'm fairly sure ebay, amazon e.t.c make a good living off their sites
and from what I have seen there are people who make an insane amount.
