I believe the Better Call Saul discs are exactly the same and the difference between the two releases is just the packaging and the postcard/record. I didn't mind shelling out an extra $5 for something a little fun and silly (it's not like an extra $40 for a statue or something) but as far as I...
I'll be picking up Better Call Saul (which, amazingly, is almost as good as its parent series) and probably Trainwreck.
Thanks for the prices, Mike! :)
