Thank you for making this point, it really frustrates me that there are so many people who will talk about how they 'rescue' an animal from a pet store, but in reality they are just supporting the store and encouraging more animals to be put in the position. As much as it makes me sad to see bp's in less than ideal conditions (and on sale too... how can you put a living creature on clearance???), I won't allow myself to get it no matter how good the deal.
If an animal's condition at a pet store tugs on your heartstrings, by all means, go ahead and get it if you've fallen in love with it. BUT unless they give it to you for free, it is not a rescue no matter how bad of shape that its in.
