1.59 is a lot of money when you have 5 snakes who eat pinkies, one of which can down 4 of them in 1 sitting. It's also a lot if you look at people who sell them locally for under 50 cents each. The boxes of frozen mice I get are 6-7 for 3 and I usually have to buy up to 10 boxes a month.
To me, breeding mice is just as bad. They stink like a garbage pit no matter how clean you try to keep them. I had a couple mice and they were stinky things. I couldn't stand them.
