According to their shipping policy.
I certainly don't see any reason why they need to order in the sunglasses to their base in Florida and then ship them out again.
Maybe that means getting the sunglasses shipped directly to me from Europe (or wherever they're sourcing them)?
It feel kinda fishy to me, like there's a lack of transparency (ironic for a sunglasses company).
At the very least they seem to have a really sloppy inventory management/logistics strategy.
