The only thing I have to add onto the other excellent advice is, when the time comes to start listing and selling, venture back in here. There are a lot of very experienced sellers who are more than happy to help you out with anything you want to know. Even if it's something like "I've just listed my first item, can people go and have a look and tell me what you think?".

A lot of new sellers have been helped out immensely with getting their listings right. We've all made mistakes when we were starting out, getting advice in here might help you not have to find out the hard way too! Some people might be very critical, but if that's what it takes to have an effective listing,accept the criticism.

Decide on whether you want to run auctions or straight out buy it now. If you decide to start with auctions, always start with the lowest amount you are willing to accept. When creating your listings, use the advanced listing tool, there are so many more option available. You will probably go into the quick lister by default when you go to list your first item, if that happens, up the top right corner is a link to switch to advanced.

After that listing is submitted, go to it on your selling page, use the dropdown on the right and select sell similar. That was you only need to adjust details for your next listing, all the other stuff will remain that you'd want in every listing.
