If I haven't posted this before here's the insider scoop when you buy merchandise from Louis Vuitton and Prada in Hawaii:
- Items are generally priced $400-600 cheaper than the mainland
- Sales tax is only 4% in Hawaii
The Ala Moana (Oahu) store is huge with two stories, the Waikiki store stays open until 11pm, and the Wailea and Kaanapali stores (Maui) have smaller inventory but can order items for you.
Travelers should plan ahead as airlines allow passengers only one personal item on the plane (purse, briefcase, computer case, etc.)
