HI Jean,
I actually purchased an ebay business on ebay

) I bought over 3000 craft patterns from a lady who was selling them on ebay. She was selling the business because she moved and even the money from the business couldn't support the cost of living.
I tried it for a while. I just couldn't sell enough to cover my listing fees. I quite during the summer while my kids were out of school and tried again to see if it was worth it. It wasn't

(
I do know there are a lot of people making money on ebay. I guess it's just finding the right product and having a little bit of money to invest for listing fees until the business takes off.
