Damn, same here i missed it too 

I used to watch that show in case they ever came across any pins for sale, the few episodes i'd seen with pins in the past, they walked straight past them.

Will keep an eye out for repeats. This one is a beauty as they feature pinball for ten minutes (15 minutes into the show). They actually show some game play and you get a couple of good glimpses at the size of the warehouse. They also show a few good coin operated machines. S4 E3 is a must see.
