Before shopping at Waikiki for all your souvenirs, go to the Aloha Stadium and find even better deals there! Aloha Stadium holds football games and other activities, but on Wed, Sat and Sun, the Swap Meet commences and there are tons of stuff you can buy. You can always haggle as much as you want because the tent 2 blocks down will sell the same thing for cheaper.
It is hot during the day, so go early. It will be worth it because you'll save tons of money.
