Where is the Hawaiian Sweet Bread?

After returning from a nice (albeit rainy) trip to Cali to see the familia, I was reminded of a Left Coast fave: King's Hawaiian sweet bread.

After putting two rolls of the stuff into my purse (lol) for the flight, I realized that this product is seriously addictive.

Once you start eating it, seriously, you kind of can't stop. So I searched four delis and three major grocery stores, and so far I've come up empty handed. Where can you find Hawaiian sweet bread in NYC? I mean really, is this too much to ask in a city where you can get whatever you want whenever you want?

It doesn't even have to be the King's bread. I would take the Lord Privy Seal of Hawaiian bread if that makes it easier to find.
