Thanks for the suggestion of using a Flat Rate box and the other pearls of knowledge I hadn't considered, such as using spray foam to seal and tighten it all up. I was planning on using a medium size fish box. I was also seriously considering 2nd day instead of overnight, since as las had noted overnight often becomes overnight(s) when shipping from AK. I had anticipated $120 give or take a Jackson to make it all happen. $19.95 for approximately half the volume is a bargain!
I will be playing a game of sockeye tetrus to pack it all in as tightly as possible and ship it on Monday to my buddies business address to improve the odds of success. I guess if it doesn't make it in good shape he can always use it for coyote or catfish bait.
I run my freezers at almost the coldest setting, -15 to -20. Slightly less "gooder" than -25 but also slightly less duty cycle on the freezer, which in theory should make it last longer.
