Answer 2

I am a former chef in Canada and we have a chain of bulk food store were you can fill your own bag will anything from candy to flour, to rice and spices.

I have bought both of them, raw or roasted, plain or salted, even BBQ flavour, the pumpkin and sunflower seeds in either the US or UK can be found at health food stores or Hispanic store, the pumpkin seed is also known asa "pepita".
