Premise: 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.

Hypothesis: 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.
