I used to be a regular eBay seller and I don't really recommend trying to sell your clothes at the moment. Most people are preoccupied with buying Christmas presents and don't have much $$ to spare this time of year anyway. I also wouldn't try selling them just after Christmas as a lot of people are away on holidays. I used to pretty much write off most of December and January when selling. If you could hold off until Feb you'd probably do a lot better.

I reckon bulk lots are the way to go, it's much more worth everyone's while. It's hardly worth going into a lot of detail (taking photos, writing a description and calculating postage) for single items that will only make you a few dollars (if that).

Good luck
