I'm not talking about the travel company first choice but instead of the large supermarket on the island of Antigua called first choice.
Here is an image of a receipt for articles that we bought and prices are in eastern caribbean dollars where 1 USD =2.6 EC approx
The following ticket was for mostly baby food for 40 USD.
At another time I bought a litre of rum for 23 ECD or 8 USD, then I also bought after security in the airport a 75cl bottle of 5 yr English Harbour Dark rum for 13 ECD - that is an amazingly cheap 5 USD !!! And this is quality rum.
You can get a litre per person of this strength stuff fortified wines such as port etc would be 2 litres. In the airport they were incorrectly informing us that is was 2 L of rum per person.

In general it makes sense to visit Antigua by staying at an all inclusive resort to save on the low value restaurants and bars.
