I'm also a fan of Rohan clothing. I especially like the very low weight of the stuff I've bought, and I really like the Barricade waterproofing system, which I find far more breathable than Gore-Tex.
I've bought all my Rohan gear from their small shop in Canterbury and I always get a discount. Before it closed a few months ago, there was a Cotswold Outdoor shop just along the road from Rohan, where I used to buy most of my walking clothing and gear. One day, I mentioned to the Rohan person that I get 15% off at CO (Ramblers membership or any of many others) and I asked why Rohan doesn't offer a similar discount. I was told that they do - you just need to ask!
In addition, a few times I've been about to buy something in Rohan and been told that the price will be lower at the weekend, or next week, or whenever. But no problem... out comes a list of codes that the person can use to give me the discount now.
