I bought the tiles back in March of this year From Homebase in Portlethen (nr Aberdeen).
when we found they were not on the shelves (a week ago)we asked them to check the product code on their system. The number does not even exist in their inventory any more - not very encouraging! Even if one of their branches did have some of these tiles going spare, there is no way for the computer system to find them. Daft!
Many thanks for the warm and enthusiastic welcome from the members of this forum. thanks for the advice regarding the tiles I need. Your suggestions have given me a few more ideas.
