I've just finished selling my exUCW clothes on eBay, and I was pretty happy I've been using it for 4 years, and have only ever opened 2 unpaid item disputes. The most important things to remember (IMO) are -

- Start with your lowest ideal price - don't start really low and assume it'll get to what you want.
- Make sure you double check the postage prices - otherwise you'll end up eating into your profits.

Good luck!
