Well it would seem strange that B&Q would actually stock anything useful, as opposed to something that just earns them a high turnover for the space it takes up.
What do you expect from a shed that sells warped tiles and can't understand why customers complain about them? It's impossible to get anything like 100% contact on the larger tiles without back buttering each affected
tile.
The Plymouth store repackage loose tiles into boxes, thus mixing up batches in the same boxes. This leads to inconsistency within each box with respect to size, shade, colours etc. If they didn't do this we might have a fighting chance of doing a half decent job, as tiles could be inspected and sorted by box, ie the quality of the first
tile may determine that of the box.
So it comes of no suprise to me that B&Q, who peddles a lot of gear that is not fit for purpose, pulls product that we actually need.
My advice is to go to your local Travis Perkins store and open an account with them. At the moment their brief is just to get the turnover in without worrying too much about margins, so good prices are there for the taking. Speak nicely to the branch manager and away you go.
B&Q don't deserve our business IMO
