My husband is in vegas and went to the cartier store in the forum shops yest and asked about a discount and they said "not on the ballon bleu!" But they did say u can get a tax break if shipped out of state so that might be an option for u to save a little? I think a service is worth 2-300 so thats about 5-6% savings so not so bad also. November is soo close!
Have him try the Cartier store at Wynn.
