I love all the responses, however RodentPro is pretty much useless to me. I currently only have one baby bp, so I really don't need more than like 5 or 10 of a size of mouse/rat at a time since it sounds like he will outgrow them pretty quickly. Also, the $55 dollar shipping is outrageous when it would take my snake almost a year or so to eat 50 frozen rodents.
My point being that it would be nice to find a place that ships just like 5 or 10 of each size, that also has reasonable shipping because they are not packing just one big box, but fit the box better to the amount that you order.
I have found Mice Direct, which does seem to have reasonable shipping as well as small ordering amounts. Does anyone have any experience with them?
