Many fakes in the Bahamas...pretty lax on enforcement.
Those Oakleys definitely fake, as is much(OK...100% fakes) in the Straw Markets.
Designer handbags are fakes, too.
They DO have some authorized stores...like for Dooney & Bourke...a Gucci store...Versacci store.
Hoffer Sports on Bay Street sells Oakley goods.NOT for $10.But they ARE real. LOL
However...prices are pretty much same as in U.S. unless there is a sale or close-out.
Might save on sales tax...but remember that you have to declare all purchases you make when you go through Customs back home.If it is really expensive, you might owe import taxes (duty).
And ...fakes can be confiscated by U.S. Customs.Although usually not if it is a single item and for personal use only.
Oh yeah...lot of fake Cuban cigars in the Bahamas, too. And the real ones STILL can't be (legally) brought back to the States...no matter what the guy/gal tells ya. LOL
