I agree with Discus, AZGardens seems to have a very negative reputation from everything that I've dug up. Lots of their livestock is mislabeled and various issues with shipping and service, overall pretty shady unfortunately. I would love to be able to get some South American shrimp stock and I want to believe in that site but unfortunately all evidence points to the contrary. I will note that BBB ratings are very misinformative though as companies just pay for the ratings they want. Good thing to keep in mind even outside of the fishkeeping hobby, alot of businesses use that BBB rating as a stamp of legitimacy or quality but unfortunately it amounts to nothing. If you happen to find any South American shrimp in your search though please let me know, I'll be looking until I can snag some!
