I've dealt with most rodent suppliers over the years and found Mice Direct and Perfect Prey to have quality mice available. However, I'm a sale buyer, meaning when mice are on sale I stock up my rodent freezer. This isn't usually feasible for those with one or two snakes. What I have done in the past, when I needed day old pinkies, was buy one or two pregnant mice from the local pet shop. I wait until the litters are born and keep them, saving the adult mice for my large corns. You can also give them away as pets if you don't need them. It's way cheaper than having frozen rodents shipped in quantities you really don't need. Another option is visiting your area reptile shows. Rodent suppliers are usually selling their items at the shows.
