I found the selection to be much greater in St Thomas. Especially downtown Charlotte Amalie at AH Rise. Also good prices. We docked in Havensight, and the liquor store that was right there had Cruzan dark in 1l bottles for just under 9 bux each. As mentioned, you also get an increased allowance shopping USVI. I believe its still 5l per person, with a 6th allowed if locally produced in USVI.
