Yeah, we get shut out of lots of stuff here in paradise. I think the following is only for those of us on Oahu, but it might change. Oldies 107.9 has a site you might try.
Half Price Deals: Home
Limited in scope and times you can "get in" to actually purchase discount cards, but looks like some good deals, if you like the restaurants they feature. I scored Crouching Lion cards at 50%. Haven't tried CL since they repoened and this seemed a good enticement beyond the great view from the mountainside. Allow 10 days for delivery and YMMV, etc.
Guess we have to give up a few things to live in the land of ever-summer.
