I'm in northeast indiana and was wondering the same thing, shipping next day cross-country is expensive. There is a place in Muncie, IN, but he only has crickets, mealworms, supers and waxworms.
Yeah it is tough getting good cheap worms. Every time i get silkies i spend 11 to 12 something. 6$ of that is shipping. And that is the 3 day, witch is never three day more like 4 to 5 to get way up here. Wish i could get our local pet store to breed them or to at least have them in stock. What other types of reptiles will eat silk worms?
