I order all of my crickets from reptilefood.com I would try them, they have fantastic pricing. And they have been great thus far, I have made two orders with them and so far the death rate has been amazing. Barely any dead for me. UNTIL the second order I made the heat seemed to have killed a lot of crickets, but I shot the an email and the NEXT day I got a replacement order of 2,000 crickets.
small pet feeders are a good website they're cheap and come alive most of them. we ordered some from them and they're coming maybe coming friday or saturday
