UH, overnite shipping isnt cheap. It costs me $55 to overnight a snake. A box of frozen mice with all that dry ice is HEAVY!

For the record, I have been buying my mice from the Mouse Factory for YEARS and they are the best I have encountered. (I have tried a couple of other suppliers.)

In fact I plan to put in an order with them today.

EDIT: I mostly have corns, and haven't ever priced a feeder rat at a local pet store, but I'm guessing they are more than $3 each, which is what that breaks down to.
