I managed an ebay store for a few months. It was a big pain in the ass. At one point we were making $400/week but we were putting in at least 60 hours a week of work (me and my partner combined), and then we had to split profits. The hardest thing about an ebay business is finding something that no one else is selling or having a better price than everyone else. If you have the right connections and can get something cheaper than the ebay market prices youre set.
