I would look for a local true tile store so you can see exactly what you are purchasing. Stay away from the Floor & Decor stores in addition to the Box Stores.

NONE. Tile is best locally. Your tile installer will have recommended suppliers for you to work with. Avoid box stores and F&D seconds places.

Visit local independently owned tile stores for a larger selection beyond the trendy stuff at your big box stores.

Not to mention that shipping of tiles directly to your home usually results in a lot of lost tiles due to breakage. You would want to directly pick up boxes of inspected tiles (or your contractor) to avoid that waste and hassle. You also can control the dye lots as you will want all of your order to come from one lot.
