Where can I sell my stuff before I return home?

You could sell your stuff at a car boot sale. They're usually are on a Sunday morning.

Thanks. Do you know any specific ones?

you can check out car boot sales in your area through this website: www.carbootcalendar.com, or www.carbootjunction.com hope it helps

you could also check out your student union...they probably get loads of similar questions..if you've got furniture etc that you want to shift then a notice at the union will probably work..
