Contact an exotic pet collector in your area and ask if they have a Goliath birdeater available for purchase. If they do not, it is likely that they might know someone else in the exotic pet business that does. Exotic pet collectors can be found by searching online or in the local phone book.
Travel to Argentina, Brazil, Venezuela, Suriname, or French Guyana to collect a Goliath birdeater yourself. This should only be done if you have already acquired the permits needed to carry an exotic spider back over the U.S. border when you return. Before collecting a Goliath birdeater, it is advised that you discuss the process with an exotic pet collector who has experience in traveling with the spider.
