Sale above was available for anybody (not just Nike Run Club members), but most models are out of stock by now. Would have gotten one myself if I didn't already have a Series 1.
It was supposed to be for NRC members only, but when the notification went out originally (I think Saturday), it didn't work. I don't know if they fixed it for NRC members between the original notification and when the general public got access to the deal ... mainly because I already have one and don't need another, even at that great price.
