When I was a kid growing up in N.Y. there were Jewish kosher delis that sold all sorts of Israeli products. When we were in Montreal a few years ago visiting my husband's family there were alot of Israeli products in the supermarket.
Here in Israel most supermarkets will carry alternative matzot (not all). They're very expensive, but taste very good. Don't know about the net, though.
Good luck with your passover hunting, but hey, it's only just Purim, and Passover is one month away. So, Happy Purim, adoni.
