You can wait for a 10% day - by getting a Fraser or Harrods ctore card (at Harrods all concessions take part in 10%, in Fraser not always). It is unlikely to get them for even less then 10% (I have been looking at those for ages, and got an oak one from the older collection, before they went up in price).
What they sell in outlets is very defferent "printed", pretty ugly imo.
