My recommendation was going to be perfski as well, as I saw they still had stock on their website. But I dont think you're going to have much luck finding places selling them discounted. Extremely popular board and we're still in summer. We have 7 or so of them left, but they too are regular priced.
The factory is out of 2013 140 Peaks, so if you can find one you better get it, as I assume there will be little if any left once close out prices roll around. We have 1 left at performance, and after that we can't get any more.
