I just bought a NIW 26oz for $170 shipped no receipt. I'd say if it's clean $150 since it has a receipt. Might be able to fetch a little more. I picked mine up and then saw people posting them for around $200 NIW. So it may fluctuate.
I noticed the price is increasing a bit on these.
Might have to go back to the store and buy more of them. Picked one up a couple of weeks ago from a local retailer for $125.
