While I do agree that NERD and The Urban Reptile both charge a lot more, they have their reasons and as long as there are places like BHB and other smaller operations you will have the choice to go else where. The animal only holds the value you put in it, not what you can get out of it or what someone else thinks.

You can shoot your own price to them, and reference BHB and the others price for the animal. The response you'll get is "I'm sure BHB and [name] would be happy to get your business", and if you don't feel that NERD's prices are right then you too will be happy to go else where.
