Costco has it back at $349, which is the price Zizzo direct had for their holiday sale earlier. Costco does that a lot - have a short-term discount for a week or so on stuff. So either they got a great promotional price from Zizzo or it's a loss-leader during an in-store event. They also have deals with vendors where all returns are accepted by the vendor, so not a problem for Costco. Must be nice to be so big you can dictate all the terms.
