Each Budget store in the Caribbean
must set its own prices because each island is a different country with different import
duties, tax and fixed costs.
In St Martin prices charged are 10% below the catalogue price
if you register an account or pay cash.
The only other one I have shopped in enough to get a good indication is Grenada
and there the prices are similar to the catalogue prices as long as you have an account and registered with your customs
clearence papers for duty free.
So get the catalogue from the store or off the internet
