AbeBooks.co.uk 10% off with Coupon Code

I was searching online for 10% off coupon codes for Abebooks, and stumbled upon this code that worked. Note: it only works for Abebooks.co.uk NOT Abebooks.com, but shouldn't matter. I've tried searching for books and the same books from the same book sellers are listed for pretty much the same prices (after converter to AUD dollars).

I'm not sure when it expires, but from experience these 10% off codes usually expire soon. Also, there's usually a maximum amount of discount (probably £10 or £15), and you can usually use for 2 separate orders before it is denied (ie. the site usually says that you have already used the codes).
