I watched it and if I hadn't seen this thread I wouldn't have though much of it... the guy needed money, he sold it to someone that had money and that person thought he could make money on it... if you didn't know who that guy was you wouldn't have given it a second thought, but because it is Collins, apparently that brings it to another level.
I have never met the guy, nor have I bought anything from there, just always was envious of having a big Jeep junkyard (one day I will have one). As you progress through life (and Jeeps), you hopefully learn things along the way. Hopefully you learn at a young age supply vs. demand and cutting once and measuring twice. You always need to look around for other deals, especially with the Internet at your disposal... if you don't and you want convenience then I guess CB is it. They will always have what you need... however, if you are not in a hurry, want to look for deals, then you can find someone else with the parts.
It comes down to if you "have to have it" vs. willing to wait. In some cases it goes one way or another.
