You can use the bot chat system which others report can be used to automatically refund you up to £200 (I have used it once for an item ~£150 and it worked easily). If you want to do more you will have to contact a customer representative.

As for what item that would be your decision ultimately. What do you want to obtain/sell? This is a great thread if you want to see what others are SEing and what experiences they have to share.

I would recommend to you to read around this forum and you will get an idea of how things operate and what you may want to do. You will find a lot of useful information that will help you along the way.

Good luck and let us know what you end up doing!
