This is the only other place I could find that sells them, but they are sadly out of stock: http://www.reptilesncritters.com/american-toads.html You could make a reminder to automatically update you if they get some in stock. You could also try putting a wanted add here and on Kingsnake.com: http://market.kingsnake.com/
Id honestly prefer to catch them myself that way i could pick out healthy and colorful individuals. I certainly want a red one too.
