No, only US stores. I usually hit the "shop for (blah)" link on google, pick the lowest price and they match on the spot. This is for stuff like shoes, something I'm not sure about sizing and don't feel like dealing with overseas returns.

It's also worth browsing Bicycle Recyclery. Sometimes I hit a sweet deal on used or NOS equipment. As an example, right now they have a Dura Ace FC9000 170mm 53/39 crankset, new in retail box for $300. Ribble has the same for $375. I got a new Thompson Masterpiece seatpost for $69 a few months ago.
