I would stock up next time that a reptile expo is near you I know this may be a little bit harder since you are feeding frozen but in my case it saved me a ton. I have three ball pythons so I cant just keep one or two rats in the freezer at a time so last Sunday at the Indiana reptile breeders expo I picked up 24 rat fuzzies for $24 from big yecks gecks they are having a show in Richmond Indiana next month idk how close that is to you but if you can go they have the cheapest rats I have been able to find. But $24 for 24 rat fuzzies was a lot cheaper then $2.99 to $3.99 a piece
