Somebody made a very good point on here awhile back about this. The stores are give guidelines on how to take care of the snake, but it's the fact that they aren't always followed. I remember a post on here from a member who stated that his petsmart or petco took good care of snakes and the proper husbandry and it was due partially to the manager who enforced the care.

I personally wouldn't get any snake from there because they overprice them, but that's just me. I prefer to help out local breeders.
