Just wanted to add one more thing re: buying online. You can avoid the last leg of the journey, the dreaded UPS, FedEx, DHL etc. truck by arranging to pick up your animals at the cargo area of your local airport - if it isn't really far from you it is a good option because you avoid having the boxes sitting in a hot or cold truck, plus you know when the flight is arriving so the creatures don't have to wait at the airport either for the delivery truck pick-up.
