I'm going to Hawaii in August, and will need 3-day rental at HNL and 5-day rental at OGG. Tried a lot of codes here, the FL state one and Hawaii bar both gave good rates, but I'm having hard time finding any applicable coupon to any Hawaii location.

Looks like most of the dollar off coupon are limited to continental US, anyone can share a usable coupon? Just want to sweeten the deal a little bit.

TIA
