Type in search terms like "crickets for sale." Several sites should pop up. I just ordered 1000 crickets from Armstrong's. They came in two days in a little screen sided box and I placed them inside a modified plastic storage box. I cut a square out of the pop-on top and replaced it with a screen top siliconed on. I used the foot tall type of storage box to keep them from jumping out and they cannot climb the sides, so good all around. The crickets are lively and healthy, the same I get from most any pet store in my region. You will basically get them for about 2 cents a cricket if you go for 1000 at a time. Shipping is only $2.00
