Costco has V2 with the pillow for $50. I'm not sure about shipping for Costco, but your local Costco may carry them in store as I have seen them occasionally.
I have an older version, same R value, as well as the ultralight version. These are incredible for the price you pay, assuming you get them on sale and don't pay full retail. Some things you need to consider is the sound that these make. I personally don't mind the sound, but others absolutely hate it and compare it to crumbling a bag of chips. These are great for 3 seasons, but if you need something for the cold, definitely look elsewhere or get the insulated version.
