Charlotte Amalie has been a trading town since the Danes opened for business three centuries ago. The USA got a good deal in 1917, purchasing 68 Virgin Islands ( and islets) from Denmark for $25 million. So the bargains you bag on Main Street come with a respectable pedigree. Some things are beyond commercial valuation - incredible sunsets, soft white beaches, warm smiles of welcome. Three of St. Thomas' richest resources.
