I order frozen rodents from RodentPro. They have the best prices for the volume I use/buy. Yes, they aren't vacuum-packed which means they won't last as long without getting freezer burn, but that isn't a concern for me. Many members love the Mouse Factory as they DO vacuum-seal, which may be better for you as you can order a larger quantity of various sizes and have them last longer. And even if you ordered only 100 frozen small pinkies, having to use two or even three per feeding by the time you get to the end of the bag, you'll be saving a great deal of money. I just got a quote for 100 small pinkies (on sale for $0.12 each, plus shipping (which is the biggest part) from RodentPro for a total of $52.15. And if you get one of those home vacuum sealers (I got a Reynolds Handi-Vac for Christmas last year), you can split any order into multiple smaller bags to improve their freezer life.
