I got this brand new for $34.65 with free shipping directly from Amazon (I got free shipping because I also bought a DVD to spend enough to get free shipping). Because its Amazon, it got delivered today (a Sunday, and I ordered it on the 25th), because buying directly from Amazon can be awesome. If you want to buy it directly from Big Finish, at least in the US, it costs $66.77

So, I got it almost half off the big finish price, and it got delivered the Sunday after I ordered it. Also, Amazon the company was the only seller on Amazon.com that was selling and shipping this in the US, everyone else was (hugely expensive) UK sellers that ship from the UK.
When I saw it being sold by Amazon, I knew I had to get it. Now I have it, and it looks pretty awesome, at least when it comes to the physical release itself. The actual stories could be horrible, but even so I don't regret getting it. The Sixth Doctor is my favorite Doctor, so this feels like something I should have. I don't know when I'll get around to listening to it (probably soon, although I'm also listening to an audiobook and I might not want to mix my listening). Still, I consider it a pretty cool purchase as a Sixth Doctor fan.
