Hi,i have recently planned to buy a Cartier love braclet and a tank solo watch after eying on them for years. I’m planning to get it at London. This is the first time I’m going to cartier. Should I get it from the cartier boutique or resellers? If I go to the boutique, do they negotiate prices on love bracelet and timepieces? Should I go to bid department stores like selfridges or harrods or buy it at the boutiques outside?
