Season 6 is a ***** to find, I finally wound up paying $80 for mine. Hey, what we will do for our hobby.
For what it's worth you can find the 6th season HERE for $100, he still has 2 available. I also found it at CEX for $85.
On Season 6 I’m hoping it was a timed exclusive and it’ll eventually pop up on Amazon or Walmart etc. 1-4 is widely available now and 5 is tough to find but I ended up getting it directly from amazon for $45 a few weeks ago. And now it looks like Season 8 isn’t a Best Buy exclusive. I’m going to keep checking eBay, wait and hope, I really don’t wanna pay $80+ for Season 6.
