Wow. That's a huge leap to take from the OP using the phrase pet store and taking a picture of a healthy, good looking animal in a clean display cage to what you're accusing them of. How about you set the torch and pitchfork down for a second and think for an extra second.
I'm sure this store has their animals priced at a point they feel is fair for them to get a return on their investment from someone looking to purchase an animal as a pet. Beyond taking good care of them while they're in the store and doing their best to inform their customers of proper care, do they need to be concerned with everything else? Good on them if they are, but I say that's going way above and beyond for what they need to be successful.
