We have been using Lagniappe Provisioning for a few years now and have always been very pleased with their service.
You will always get only the freshed provisions avialable on the island ( Simon shops at many of the Supermarkets to insure freshness).
If a requested item can not found fresh, they will not provide a "stale" one. It will be noted on the delivery recipt and credited back to your Credit card. (F.Y.I. I have no affiliation with Lagniappe, speaking from past experiance)
Simon (Mr Lagniappe himself) Loves to deliver heavy provisions like 5 gallon bottled water and cases of Belikin Beer especially if you are staying on the 2nd or 3rd floor so don't be shy to order large quantities of heavy items as he told me once that he loves the exercise.
Enjoy your stay @ Tranquility Bay it is a really cool area of the Island, Very beautiful and has a neat Bar / Resturant over the water. Great Snorkeling right off the deck or beach, we usually like to stop by there for lunch at least once every time we are on the island.
I want to be just like Capt Jeff when I grow up!
