If you can't find one in your stores you can buy online, that's where I got mine from. I want to get the mini's next
They also have a bundt form available that can be filled!
The shipping time is horrible though so if you can find it in the stores go for it. I waited over 2 months to receive mine.... but here's the link anyway. I will say it was worth the wait! I received the dome pan free of charge, in the kit, as well as the round/regular pan. The possibilities are endless with this thing and the website even has pics of cakes that have been done by other people who have bought the pans http://www.bakenfill.com/
