My local petstorechainshop (funny word) charges me 1,49 € for feeder and 1,50 € for fancy mouse, the difference between both is age and size and you can "choose" the fancy ones, the fancy mouse being younger and the feeders being retired breeders or "damaged" fancy mouse. I bought my breeders there and my best buck had a sliced ear, but is a satin coated guy and great dad.
