As part of SurfStitch's current deal where they have a minimum of 50% off all sale items, you can often get discounts in the multiple hundreds of dollars when such a deal is run.
Retails for $560 on the Nixon website and can be found for ~$380 on a website called Dressinn.com but definitely nowhere as cheap as this.
Supposedly the sale ends tonight but SurfStitch often extend these things.
Haha they're dreaming if they think theyre going to sell a quartz movement with mineral glass for RRP $650,or even at half price for that matter. For that price I'd much rather get a Seiko Skx013 or SKX007
