I talked to my manager/friend, and he said he ordered 15, and they were supposed to arrive in the store today, but didn't.. He also said mortality rate is pretty high, so keep that in mind. He said his supplier is in Chicago, and I'm not sure where the main distributors are located, but if Iowa is within the range of ours, you might be able to get a Petland nearby to order some, assuming they use the same chain of suppliers.
I just checked for the nearest Petland, which is in Iowa City, 2:30 away, and I'm 5 hours... lol. Soo.. if you're going to stop by Iowa City, you could call a couple weeks ahead and ask if they can order some.
