I have been to the rez stores outside Vernon BC, and they carry BM products with ounces as low as 60.00. I am sure the 180 dollar ounces they sell are the better of the two levels of product though. The cheap ounces are more than likely tumbleweed.
The stores are saturated there too, I think they call it the green mile.
I read a news story about one place shutting down, and they attributed it to the oversaturation of stores, and too many white people opening them up on their land instead of natives.
