I am currently looking to give away three tiger salamanders for free as long as whoever wants them pays the shipping. However, I am not experienced in shipping live animals and I want to know what is the best service( UPS, FedEx, USPS, etc.) to ship these animals in terms of reliabilty, cost, speed etc. They will be shipped overnight regardless of the service but I want to use one I can trust. I know that this is not a fish question, but I also know that alot of you have experience with shipping fish/ live animals and Im hoping to gain from some of your wisdom.
