It's been pointed out to me by a couple of people now that they can't understand why I have so many dvd's, and why I keep buying more. I must have 150+ dvd's, 20+ box sets etc. I'd never really thought about it. However, as I'm always buying new dvd's, I rarely watch any of the older ones. If that's the case then maybe it makes more sense to rent? What do people think. is there an optimum number of dvd's to own? Can you have too many?
