You can try contacting Barritt’s and asking if their Ginger Beer is available in your area. This is the ginger beer that is used when Barritt’s makes the Dark n Stormy cans for Goslings. Ginger beers are not created equally. Then just buy the Gosling Black Rum (available everywhere) and mix it yourself. It will taste the same as the cans, but not as convenient. I have been drinking the cans for 20 years, but when on the island the drinks are always mixed… like the wicked ones at the RBYC Newport Race party.
