CompMaui

There are several Apple Computer retailers on Maui but I’m going to assume you are looking for the Mac Store (MacNet)

I believe they also sell some amazing home theater equipment and have an amazing showroom (though how can it be anything but amazing when you are selling 30″ monitors..)

Maui Apple Store:
444 Hana Highway Suite H - Kahului, HI 96732
Ph: 808.893.8484 / Fax: 808.893.8383

Mon - Fri: 9am -5:30pm, Sat: 10am - 2pm, Sun - Closed
