Maybe it sounds dumb but I love this product. It's not too expensive and I know to use it! Thrive also has a website that even has a section for 72 hour kits. You can buy the premade packs or buy things separate to create your own pack.
My friend Misty who is a consultant has just made getting your 72 kit together SO much easier. By having giveaways every week and by breaking it down week by week. I'm so excited for this I can't even tell you. The things she has suggested so far are brilliant. If you would like to follow along here is her site.
I'm defiantly going to try and do this so that at the end of 26 weeks I should have most of my 72 hour kit together without breaking bank.=)
