As other's said there was a recent price increase by Cartier in the US, so it's unlikely we will have another in the next 5 months. SA's do not get that much notice, so usually once you hear about it there are 30 days or less before it's happening. If you are buying it in Paris, for the most part it's for fun or a as souvenir of the trip. I've rarely seen where it ends up being cheaper than just purchasing here even if you take into account the return of the VAT (and I had an occasion with issue of the VAT not being returned), once you take into account the exchange rate, currency conversion fee by most credit cards if you pay by card, duties etc. Wishing you luck whatever you decide.
