Ah now, this is my exact worry. When it comes to price matching, all interest in professional customer service seems to go out the window. The fact that you have dared to take them up on their offer seems to automatically remove you from the "valued customer" bracket and you are reduced to something stuck on the shoe status.
Adding the fact that I'd be buying remotely and not actually seeing the item I'm buying, I would be concerned that I'd end up with a scabby ex-demo foisted on me that then becomes a nightmare in waiting as I try to return it..etc!! Pity, it's the convenience of a Saturday delivery that really attracted me.
