Electronic gift certificate ideas in Kapaa or Lahui HI?

My friend is in on Kauai for a few weeks and I'd like to send her a gift card electronically for her birthday for something local but I'm unable to find a good list of places there. I konw that there is a wal mart o kmart in kapaa, but would prefer something like borders or B&Nobles or even a local bookstore, cafee, etc Anything :-0) that she could enjoy locally. Thanks
