I just got an ENO Guardian Bug net for $39 with free shipping from Campgear.com. They have a 30% off sale with the coupon code SHIMFF30.
Most of their stuff is listed at MSRP, like the Guardian was at $55, but the 30% and free shipping brings it down to $39, best I've seen on the ENO Guardian in a long time.
I already have one ENO Guardian, but at that price a second gives me a second homemade hammock I can use to get a friend or noobie out into the woods.
BTW - the discount code was posted by an employee of campgear.com on backpacker mag forum, and he took a little heat for not disclosing he was an employee when he first posted. I have no affiliation with him or that company other than I just used the discount to get an ENO guardian
