Hey all. I feel for exactly the same modus operandi. I intend to follow the credit card company complaint avenue that another post suggested. I will also follow through with them first and see what happens.
FYI, I purchased a Leica D-Lux 4 which was advertised about $150 less than most other retailers. I was given the usual call back to verify cc and shipping, with an attempt at ad on sales etc and an upsell to the "U.S." version (the one online was apparently the Japanese version and would take weeks to arrive, even though it had the same model number.)
Amazing that they could perpetuate the same fraud over and over the last few years.
