Way way way too much. I basically collect TV series on DVD (this summer alone I got three seasons of How I Met Your Mother and one season of Futurama), and I just LOVE TV shows a lot.
I probably spend close to $50-$60 a month, but I'm trying to budget myself; I love movies, too, and while there are a couple I want to see in theaters right now I need to limit myself.
I'm still seeing Inception again, though.
