Amazon offers Prime members the Stanley 64-oz. Classic Vacuum Insulated Growler in Hammertone Navy for $35 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's the lowest total price we could find by $6. It features stainless-steel construction and purportedly keeps beer cold for 24 hours.
Of note, it's also available in Hammertone Green for a buck more.
