I was just wondering if I am paying too much or if I am just cheap. My local pet store charges me $3 for an adult mouse (I haven't weighed one but they look kinda small to me), but lately he has been out of adult mice and selling me little ones (I weighed them they are about 15grams) for $2.50. I only have the one BP who weighs in at 167 grams so its not breaking the bank yet, but I was just curious.
