Catching deals is good and all but if you keep throwing your money at every cheap male you see your never gonna be able to buy what you'd really need like a well started female. Start looking for deals on the females or perhaps just skip buying snakes on one show ( as hard as that may be) and save your movey then you'll have something to work with when it comes to getting a good female next time around.
Remember the females are the ones who have to put on the major weight while the males can breed within a year, so while you may have your males all ready to go, your gonna end up waiting still for your females to get to appropriate size unless you are just going to get large normals
