There are no dogs, cats, birds, or whatever it might be "selling" these days.  They don't give animals away for free as long as you pay the "shipping charges".  If you plan on sending them money, take that money out in the backyard, set it on fire, and roast hot dogs over it.  That way you will at least end up with something because if you send it to them you will have nothing.  If you want a pet, go to the shelter, rescue an animal, and remember that you get to meet it and take it home the same day.
