I think they are great looking snakes, and unless you were planing on using them for breeding, does it matter now they are norms or not? I have a beautiful normal who has very few aliens ( only 2) and think she is one of the most beautiful snakes I have seen ( ok so I am a little biased!).
As for the $100 for the pair, I think if you didn't have access to a show, or the ability to order from a breeder, then you got a fair price for the pair. Sadly, Craigslist is full of scammers. Up here, most of the morphs found on Craigslist run much higher then they would anywhere else. Example, I contacted a guy who listed a male spider. Turns out he wanted $400 for him. Good luck with that!
As long as YOU are happy, then $100 for the pair is worth the years of joy you will get from them! Congrats on 2 beautiful snakes!!
