Has anyone any experiences with Gibbs and Dandy builders' merchants?
They're part of the Saint Gobain empire, although seemingly different from

I haven't used the one here much since they took over the local indy

As usual for BM's, they don't quote prices on their website.

Yes that's pretty annoying, at least Travis Perkins will let you see
prices after you login.
