I did my own search to find larger prey on the internet, and it didn't end up the way I wanted it to. Rodent pro seemed to be the best, but I live so far away that shipping makes it seem like it's really not worth my while. "Rodent Gourmet" (the company that supplies petco with frozen rodents) does have rabbits, so I thought I could go to my local petco and see if they could add some frozen rabbits to their weekly order (so the shipping wouldn't kill me again) and for whatever reason, they wouldn't do it, so now I buy live rabbits locally, prekill them, and feed them to my snakes. The "secret" I found was to not go to petstores, which around here mostly don't sell rabbits, and when they do, they're the pet variety that cost 30 bucks. I go to feed stores. In my experience, most feed stores around here sell rabbits, chickens, and quail. I'd visit a couple and see where the animals look like they're cared for the best (some places I've found take better care of the animals than your average pet store, and some really really really don't) and you should be in business. At the feed store I typically go to, small, medium, and large rabbits are $8, and collasals are $10. Not as cheap as rodent pro, but I don't have to pay shipping and they don't get any fresher.
