I'm not sure if you are going to find Amarillo anywhere. I'd start finding a substitute now. This is one of the few places that even has Simcoe. I think he said he has more coming in.
Yes I would be in for 1 lb or 8 oz of Nelson Sauvin, I've been wanting to try them.I too would love to know if you anticipate getting Nelson Sauvin. It's definitely my hop of choice and there are not a ton of places to get it. Found one place that still has them, but with shipping was going to cost me nearly $30 for 6oz.!
