The initial batch is always the most expensive as die hard fans and scalpers will snap them up and they know it. You are then left to the mercy of the second hand market which adds even more. So, the dilemma is do you pay up front, securing a steel or wait to see if more are released at a lower price? After six weeks, anyone who wants one already has one so the prices do drop, but as I said, do you take the chance or pay up-front? Someone is selling the Loki season one one-click for close to £300, that's not far off what I paid for both season one and two box set.
