HOW CAN I DO EBAY BUSINESS?And what can I sell? what is the ideal selling item?

It's got to be something you know about really, you’ve to know a good deal when you see one. What are your interests and how much space do you’ve and how much money do you want to make? Storage can be a real issue. I run an ebay shop and it took me about a year really to see any money. I had to learn what things are worth, how to write descriptions that sell etc. You can make some good money but it will probably take a tiny work ad some trial and error.

Good Luck
