Thanks to everyone who's posted all the helpful info about the initial Zappos pricing. Was able to get the lower price on my first try - just got off the phone with a VIP rep (who was awesome and super nice) who hooked up the $49.99 price. Politeness goes a long with the reps. Told her that I had them in my cart since yesterday then was surprised at the price jump when I went to pull the trigger on them today. They have definitely been made aware of the priceing error/mistake. She took my order on the phone and then processed an immediate $20 adjustment for each pair after she placed the initial order at $70/pair. Reduced my order for 6 pairs of black sails from $420 to $300!
Thanks again, you guys are great. Best of luck to everyone, and stay warm fellow East Coasters.
