LivingSocial has a special 10% off promotion for their travel escapes with promo code ESCAPE10. This promotion is valid through October 11, 2015. See the full terms and conditions here. Their Hawaii escape deals page is here. One of the deals that we think is an especially good deal is the this one for rooms starting at $129 at the Courtyard by Marriott Kauai. We love this budget-friendly accommodation as you can read from our review. You can use the 10% off promo code on top of the deal price.
