If you have size 3-4 feet, I have a code that can get you a more or less free pair of designer folding ballet pumps (the type you keep in your handbag for when your high heels start hurting your feet too much).
to http://www.redfootshoes.com Redfoot, look in Clearance where there are lots of pairs at £10.50 and use the code REDHAIR1 to save £15. You will have to pay postage of something like £4.99, but if this works you'll be getting a pair for 49p.
Let us know if it works! I just bought a pair off Ebay and they look great and are supremely comfortable.
