Somewhat of an aside, I'm pretty sure at least one of the items was on amazon at that price in error. The manufacturer/retailer charged a large shipping cost (40lbs) when ordered through their website while on amazon the shipping was free. The item still shipped from the seller (not Amazon and not prime), so I saw it as likely either an oversight or an error because what I paid could hardly cover the shipping costs of such an item.
