Take the following as truth: Neither Martinique nor Guadeloupe enjoy duty-free status (apart from the duty-free shops at the airports), but almost everything from France is sold at mainland French prices, well below what the items would cost in North America.
Then the following statement: "Minus airport duty-free shops, Martinique and Guadeloupe don't have duty-free status, but prices in France are far less expensive than in North America." is true, false, or inconclusive?
