So I want to buy the Rent movie soundtrack. It's $23.99 at Borders, and I can grab it tomorrow. I was browsing iTunes so I could listen to samples, and I can get it there for $16.99, plus I can have instant gratification. But! It comes with DRM. Which I can remove easily enough, though that's not the point. I guess I go to the store tomorrow.
Today's cost of standing by my principles: six bucks.
