Has anyone ever had an eBay business before?  

I personally never had an eBay business but my fiance's brother does and I think his business has a net worth of like $500,000.00 or more. His sales really skyrocketed during the holidays, he was calling us to come and help him because he was swamped with orders, lol. My fiance has his own store so I'm not sure if that qualifies but he just sells different things he finds at good prices, but he makes an average of $200 a month, so I guess thats pretty good... it helps with the bills.

I would never think used tennis balls would sell like that, lol. But I guess you never know with eBay and the people that shop there. Where did you get the used tennis balls? Did you just go around tennis courts and get them out of garbage cans? lol. Are you still selling them?

I use to have an ebay store where i would sell items through and affilate store i made alright money but they keep raising there fee's and sometimes paypal can be a pain so i cancled my store
