For those of us not cutting edge enough to have binned them years ago...
£20.00 off any pair at The Hut - enter 20UGG at checkout (expires midnight I think)
25% off any pair at Javari - enter JAVABOX6 at checkout (expires 30/09/11)
Javari's offer is obviously better but they didn't have much stock. I bought a pair of classic short chestnuts for £125.00 from The Hut.
The codes are from Martin Lewis's Money Saving Expert website. They've confirmed with The Hut that the Uggs are genuine but sourced from abroad.
