The pet supermarket in Pensacola is not very good, they dont have a very good selection of reptile supplies, they only sell mice not rats. I went in there once and they had some BP's in there and they were very skinny looking and there was 3 of them in a hatchling sized enclosure. The enclosure also had small air holes in the sides connecring to other tanks on the same rack, so if one reptile gets sick they all get sick.

The one you went to may be the exception though, it really does matter who works there and what they know.
