Question for you all....

So when we buy online from home, we have the luxury of searching reviews online for certain breeders and we come to know their reputation. My question is at shows, there are many "local" breeders and some that may not be as well know but don't have a website. Has anyone had issues buying form the shows of what was sold to what you thought you were getting?

I will be going to the upcoming Hamburg show, and I ask as am looking for a few BPs and just curious if there are no real markings for things such as Het Clowns, Albino etc, do we just really take a chance and trust they are Het?

Thanks.
