Fresh Mysis Relicta Shrimp

You probably use 8oz bags and yes 16oz is 1 lb.
I usually ship it greyhound or another courier. Product is shipped in styro boxes with ice packs, and it keeps just fine. For International shipping I use dry ice. And right now the shrimp is comming out of Okanogan Lake in Kelowna B.C. Canada.
Heres a question for the list.....
What is a fair price to pay from your standpoint???
8oz?
16oz?
2.5lbs?
5lbs?
