Where not to buy.
A word of warning. I have just bought over 20 square metres of porcelain tiles from the spiderman tile place on the Catral road. I appreciate they have a no returns policy but every single tile was damaged. It appears to be an issue caused by the factory packing department not the retailer. However I bought them from him and they should be accountable in my opinion. When I returned to try and resolve the issue by swapping the tiles if need be but he was very dismissive and said it was my problem. Maybe you would be better advised buying tiles elsewhere.
