If you look closely, it says" sign up now and be notified when this item is available". Sorry, I would do it.
The "Sign up to be notified when this item becomes available." is something new, when I first posted he had some for sale. Another odd thing is alot of the items were 434.86. He had an iphone 5, nikon 3100, nikon 3200 and a couple of items all for the same exact price. Now it seems even weirder that it changed from having a price on all his items to the unavailable notice.
