Stores do exist that sell designer morphs and some really nice ones at that. A place near Monroeville, PA called the Enclosure will sell high end morphs. They don't tend to keep more than pastels in the store and they tend to keep the morphs in the back. Normally you order what you want from a book they have with pictures and they will place an order for you from breeders they have arrangements with.
Granted they also sell venomous snakes as well as larger snakes such as retics. Additionally you sell four legged herps, spiders, and tropical birds. They also sell supplies and cages.
If you go there ask for Jason and tell them Shandra sent you. Shandra is my wife and I always teased her when we were living in Pittsburgh that Jason was one of her boy friends with as much as they saw each other when we had to pick up our feeder rats/mice on a regular basis.
