Especially France. First go through the entire catalog and write down a comprehensive wish list. Then, for every item you wrote on your wish list, find the current prices in the US and add your local sales tax. Now when you go overseas and go into LV you can easily figure out how much money you are saving. In Paris, it is close to 30% difference. You can find out many of the French prices in advance by going to the French LV website as it lists the current prices unlike the USA website. Having this info handy means when your DH or SO gripes "do you have to buy that?" you can point out how much money you are saving. I did this before a trip to Paris and I was able to quote US prices to my DH and he was much happier buying me 2 Lvs since he was saving $$$. Another time in Stockholm I was going to buy the new Rosewood vernis when I saw the just released Neo cabby MM in blue denim. I didn't know what the US price was, but I was pretty sure it was going to be cheaper in Stockholm, even with the lousy exchange rate. Well, I was right and I saved my DH close to $400. The one thing I didn't do was go to my local boutique to check out my wish list since I thought it would be rude of me to waste a local SA's time (and maybe keep her from a paying customer) and then say "well, thanks, I'm going to buy it in Paris now." So my list was pretty long but my SA at the Mothership was patient and some bags got immediately disqualified with just one IRL glance. Hopes this info is helpful.
