Store selling water frogs, are their small tanks good enough? Is there anything I can do about it?

I went into a Hallmark store today and saw they were selling tiny water frogs. There were 2 to each "tank" and the frogs were about the size of a half dollar. There was only about 3-4 inches of water in there and no fake land or anything in there for them to rest on. Maybe I'm just over reacting and too sensitive when it comes to animals, but are these habitats good enough for them and are they allowed to sell these frogs in their store?
