Virtual Villagers Games?

Does anyone know where I may buy the virtual villagers game for 5.00 dollars. I am a single mom and I like to kill time before I go to bed when my baby girl is a sleep. I had seen this game online. I am really tight for money right now or I would just pay the 19.95. The only reason why I have the web is because I need it for school or I would just turn it off. I tried searching but i keep getting ( if you have my members card you will have a discount) but that is just adding on to what I do not have. The only reason I want Virtual Villagers is because that game will last a long while, at least a year or so for me.
