I didn't know Top Hat was in K-Zoo. I live in Grand Rapids. I get them at the show once a month. I only need 500 of them. I get them for $9 at the show. 1000 costs $13, but I have been doing really good on die offs where they barely ever die anymore, so they last a month. I get my Hornworms and supers also from there. Read the top hat faq though. If you think you have dead ones on delivery they might not really be dead. You can revive them or something like that. Read the faq it might help you out. One of my chams stopped eating crickets. It's weird how they get picky, so right now that one is eating Dubia's and Superworms.
