SN sources? USA

[Timeleft]

I am having trouble finding an SN source. I tried to buy from the DD site but they canceled my order because they said I didn't meet the specified criteria. I looked at LS but their policy to buy SN is obvious and I don't think I could get by. Then there's LW but they're out of stock and the amazon articles about the recent SN deaths makes the probability of them selling again very rare. The only thing that seems obtainable is from PC but it says for curing salmon eggs so I am not sure if it is good enough. Someone please pm me a source if you'd rather not discuss.
