ARS is a little more expensive I guess, but they also vaccuum pack their animals... and the next time I order, it's going to be a big one, and I want the rats to keep.

I've also heard nothing but good about their products, and just want to try something different, see how it goes.

EDIT: They always have quite a few animals for sale at the show, no matter when you go---though, it's true, if you wait till spring, when everyone's hatching and having litters, you'll find a bigger selection.
