In future, pets in the store will cost less. I can't reduce the prices now, because it would be unfair to people who have already paid for Cerebus etc, but I will put cheaper pets in there next time. I hadn't really done the math when I was setting the prices

For those who are intent on completing your collection: if I were you, I would view the shop pets as a seperate collection from the free pets. We purposefully refuse to sell old rare pets like sun dogs/zebras etc in the CS store, because that would create an unfair advantage on those who could just pay to complete their collections. The store pets will always be different to free pets, so that there is no overlap. You can find someone to trade with if you really want one, but try not to be upset if you never have them. They're part of a seperate collection. I believe a complete collection of CS pets does not include anything from the store, those are just bonus pets or items for people who continue to support our speedy new server.
