It would be cheaper to fly to Paris and buy the purse from the Louis Vuitton store there. Yes, I realize it's a long way, but this is for a purse, remember? The Champs-Elysees store is the granddaddy. You will see women from all over the world (mostly Japan) bowing and praying in the front...
Eyes on the prize, Veruca....
(and yes, I've done this! The bags are about 1/4 of what you would pay in the US, perhaps up to 1/3 due to the value of the dollar vs the euro)
