Impulse Buy

I just ordered the first season of I Dream of Jeannie on dvd from walmart.com. It was completely impulsive because I had just seen an interview with Barbara Eden and Larry Hagman on CNN. Unfortunately, the show ran for 5 seasons, which means I will be buying dvds for a while. I would like to get Dr. Quinn or McGyver but I'd be in the poor house if I bought those two complete sets.
