My mom says buy your pineapple in a good market at home-they are the same pineapples...at least nowadays you are likely to get really good fresh ripe ones at a market here. Shipping is expensive and you have to deal with your luggage every step of the way with the new security procedures.
Usually...at the airport or in various places they have cases of fresh pinapple that contains about 6 and can be shipped for around $30. they will take all the shippping info and send it the next day, so that when you get home it arrives shortly. It IS worth it, and it IS the BEST you will EVER eat!! Do it for sure, you won't regret it. I promise you can't find anything like it here in the states...and the comment about the macadamia nutz..right on!!Especially chocolate covered!!! Buy several bags! Shopping wise...it depends what island you are going to...Oahu has the best shopping at the ________ mall. I'll get back to you on its name. Good luck and enjoy!!
Okay, so I have the name of the mall...Ala Moana....it is wonderful!! But here is a website that talks to you all about shopping also just type in shooping in Hawaii, and all kinds of pages come up... http://www.visit-hawaii.com/4star/Shop.2html
