i personally hate all B&Q tiles,usually different size tiles in the same box and sometimes different shades,usually broke corners aswell.
for a few pounds more and with my trade discount you can get a decent tile from a tile shop. i know they have made an improvement in the tiles they sell but i dont look forward to using them and try and put the customer off going there.
wickes tiles are just a no go for me,will not put them up,terrible tiles and when i called and told them they just said "yeah well nevermind". 3 different shades of white in one box and 3 different sizes.
must admit in my local B&Q i havent seen these tiles but my local isnt that big and the tile choice is quite small.
