They are 60% off with free shipping over $35 on their website. I bought one of the Rush 12 packs for like $42 after tax.
They are a good pack and well worth $40. I am not sure they are worth their full retail price but for $40, they are worth it.I'm tempted. They seem like a good deal and a bug out / emergency / survival bag seems like a good plan.
The smallest 12 looks fairly large on its own.
