hi everyone,
I purchased my RG Classic Love bracelet at the Cartier boutique in Cozumel, Mexico (November 2018). Price was $100 less than current U.S. price and I didn't pay taxes. Mexico also offers money back at the airport for luxury items in excess of a certain amount. The Cartier associate explained to me that the price for jewelry sold in Mexico from Cartier already includes Mexican taxes. As a non-Mexican resident I am able to get that money back (similar to how VAT works in Europe). I purchased the bracelet in November 2018 and I was refunded the money last week. It takes a bit of time (not instant like in Europe) but I ended getting refunded around $550 dollars.
Hope this helps!
