We have tried couple of times in Honolulu. It accepted our orders all the time but always failed to deliver. You get a message that it failed and a charge may temporarily appear which will be zeroed later.
However, amazon.com continues to show these pages and the ordering app is working great. Don't expect any delivery.

One of our neighbors got some grocery delivered. However, the order was not delivered in its entirety as the inventory does not adjust automatically.
