I'm bumping this thread to see if we still agree Paris prices will be less than NY? We have 8.5% tax, here, so even as the dollar falls, perhaps if one could purchase in Paris and not ship, one could save a decent amount? (longchamp pliage carrier for importing, perhaps)
Although the USD is down against the Euros, the NYC Tax and the European VAT still makes the purchase in Paris a better deal...so:
with NYC tax @ 8.5%: USD$8137.0
with European VAT refund @ 12%: USD$6600
savings of: over USD$1500 (WOW)
But consider:
Availability of the bag at the destination...unless you are open for what's available and just looking for souvenirs
Risk of bringing in without declaring through customs (I believe it's 10% over the allowable)...I don't risk with US customs.
We're leaving for Russia in March and we'll chance it there in getting another one there (doubt it) but early June with Costa del Sol, Nice, St. Tropes, Cannes, Portofino...perhaps better chance to add one or two more...nice souvenir!

What else do other tPFers think?
