No clue where in the US you are but assuming that this is the company...looks fully legit:

Not to say anything bad about the Mid Atlantic Stocking Co. which serves the Fish Haven Farm I would recommend Zetts Fish Hatchery anytime.
These folks have been around for ages!!! I think I first encountered them back in the late 1950s and I ordered plants from them back in the 1970s (around there sometime!) and they offer a good variety of fish as well as handling their own delivery though they also let customers pick up the fish at their farm! I am glad to discover that they have finally made it to the internet. See link below.
