Is there a difference in tile according to the price you pay? For

I do not think so, although I am not in the tile industry (just a do it
yourselfer). From my limited experience, I'd say it is easier to get tiles
ditry that way on the cut edges. If you have whole tiles, maybe they do
not have the blotch on the non-cut edge? Anyway, that's just a hunch.

Maybe there's someone else who knows more than I that can answer this?
