Want $40 for $20 bucks? Of course you do. Get it at http://govity.com Their Whole Foods promotion is the first one I am trying out but it really worked seamlessly. Plus it looks like their website keeps track of all the deals and I can print them out later or when I am ready to use them.
They are supposed to have 50 to 80 percent off deals, and different kinds of things, all local to Maui.
