I have been selling them for 2@ $45.00 with free shipping. I'm not sure what Beck is charging for shipping.
As for a group buy, I would have to contact Life Straw and see what I can do. I'm pretty much at the minium selling price now.
If you guys are interested in a group buy, contact me and I'll see what can be done. I have probably 50 to 70 in stock as I type this, so I wouldn't have to order any.
Hmmmm.. I had never heard of this product until this thread, but after looking into it, it looks like something I'd be interested in. If you do have a GP, I'd participate.
