Not one at the moment that I know of, their sale and recent promo only finished a couple of weeks ago. Anything they do is heavily promoted though and lasts a fair while, so sign up to their mailing list and keep an eye on their Twitter feed, you won't miss it then. They never do personal codes or discreet "members only" offers or anything as prolific as e.g. Boden, if that's the kind of code you're hoping for (as far as I know anyway, and I would consider myself the sort of customer who would get one if they did!!)
When you do, buy online and sign up to Quidco to get additional cashback. Buying online also gives you a guaranteed refund option as you can only exchange when buying in store...online customer service is fast and good.
