Given that you only have one snake that isn't full grown, bulk ordering makes little sense. So I'm not going to recommend any of the quantity frozen businesses out there. If you have reptile shows in your area (I don't know where you live otherwise I suggest what ones I know about), that is the way to go for smaller quantity frozen or live food. You can also scan FB Marketplace or Craig's List in your area for small breeder operations. Once you corn is an adult, I would switch to buying food bulk shipped.
