I would go crazy with the store credit lol. I would most likely need one of those children leashes to keep me from running everywhere lol!
I hope to start out with a pretty good sized colony too. I have only 3 mealworms left, and one of them is in it's cocoon about to be an adult pretty soon here. I will try to get one more mealworm to at least grow but if it does not in the next week then I will just try to breed the two I already have.
