I use rodentpro. I'm not sure why it would be that much, did you get that as a online quote? Or a person on the phone? Maybe it was a glitch?
I know it's expensive, but I've never had it that high for one box. It does pay to make a FULL box order, and that's why I like RodentPro, bc they let you fiddle with a online quote to find the most full you can get the box with the things you want to order.
