Designer euro tiles. Worth it or not ?

On occasion we find ourselves in the boutique tile shops that display the Italian and Spanish tiles in magnificent showcases. Even after negotiating some builder discounts the stuff tends to cost a lot, have lead times exceeding an Italian summer holiday, and risk of running a tile short is held by the misfortunate person who did the takeoff, typically me. Despite these obstacles, the tile install is one of the project highlights. While my aversion to throwing money at a project is well documented, especially for materials invisible to the buyer, the tile is among the most prominent interior features.
