Charles Tyrwhitt are currently having a 25% off sale - check the link to have a browse of the items. But this is even better - they are also offering an extra Tenner off when you spend £50! I've never bought from this company myself - but I've heard good recommendations about them, both their men's and lady's ranges.
Details: Isn't life like buses? You spend ages with nothing much going on and then two exciting things happen at once. Our new Autumn/Winter 2006 collection and the chance to offer you 25% off everything in it. And it's as old as the hills, but we still have our three-month guarantee.
