Good fly agaric source in the US?

I want maybe a kilo to start, maybe less depending on price. Before on that larger site I saw people in the balkans were selling whatchacall it, the more powerful variant, panther something, for around 250 a kilo. So I was hoping for less in an in US purchase, customs is a removed here, even before this administration. They seized shit I ordered before and were real shitty about it. Even though it wasn't illegal.
