Dulux Heritage - where to track it down?

[emeraldgirl1]

I'm probably being really dim but I can't seem to locate Dulux Heritage range in Homebase/B&Q etc... I really ideally want to find some sample pots of Heritage colours too but can't even find the actual thing at the moment!!!
It's probably a very basic question so apologies, but if anyone could tell me how I find the Heritage range and try to get some samples, that would be so helpful!!
Is it a Dulux Trade thing, and if so where can I find the Trade range?

your nearest Dulux Decorator Centre.

We recently bought some from b and q. Can you order some from their website I to store? The pressed heather looks a bit like lilac on the walls.
