Ok now its starting to make sense, I can see how its not to cost effective. Thanks for all the info, I think you just desuaded me from breeding rats.
The shipping on frozen rats is what kills me, but I just realized the rodent pro, and some other sellers use greyhound, I'll see if the price comes down from that. By the way Rodent pro is still charging me 297 in the quote must be the shipping to my area.
