Petco rapes us on ours.

Its $1.99 for mice
$6.99 for a medium rat
and $5.99 for a small rat.
And you do the math, I go in each week and buy 3 medium rats, 1 small rat and 3 mice. I'm spending 30 some odd bucks each week...yes I am going to breed my own and freeze them very soon. That doesnt even count for the cost of housing them being that I cant get everyone to eat each week so I end up putting up with rats and mice every time, right now I have 2 medium rats and a mouse shacking up in here....I'm going to charge them rent!

What gets me is it's $7.99 for 3 small forzen rats. WTF? I know with cost for feeding and everything adds up, but what about killing the rats, freezing and packaging them and then running the cooler to keep them frozen? Why would frozen be that much cheaper.
