I want to exchange it for a different color can I do that when I get home to the USA?
I think so, as long as you have the original reciept!
yup i did that twice. I exchanged my bags when i got home(manila, philippines) just show the receipt.
you can exchange in any LV store in the world.
would you have to pay the price diff when you exchange since its cheaper in france???
if the same item No.
Nope I've had two of my gf's do this before from Paris and you can only exchange it but no price difference whatsoever.
