Where can I find Wonka Chocolate Bars?

I remember being able to buy these from a store back when I was a kid, I'm 16 now and I can't find it anywhere, not even in special confectioneries. I live in the Philippines by the way, most of you live in the U.S. but could you tell me the name of a store there that sells it? I could always ask my grandparents to bring me home some.
