Our island might be tiny in size, but everything needed for a sophisticated lifestyle is available. Especially the selection of luxury items is fantastic; you'll can browse isles and isles of French wines, find all famous Cuban brands, shop for gourmet food including oysters flown in from Europe. There are liquor shops catering to the most exotic tastes, and the Adult Toy Box will help to find that pleasing... toy.
There are 'Home Depot'-style and size home improvements stores, there is a 'Costco'-style wholesale/retail store and there are several furniture shops - all there to outfit that new beachfront residence you just bought.
As the commercial hub of the Lesser Antilles, St. Maarten's car dealerships are absurdly oversized for the local market: not only are most of the Japanese and Korean brands represented, along with the European manufacturers Citroën, Renault, Peugeot and Volkswagen, but even BMW and Mercedes have dealerships!
Whatever products are not available on the island can be ordered in the US and will be shipped down within days: this is true for orders from Amazon as well as all the way to used cars from Miami. As the island has no customs, there is zero red tape and very little cost to live a lifestyle similar in convenience as living in the US.
