Here is my experience:
• I took my family to see the Incredibles - cost $7.50 x $5.00 = $37.50
• I like it so much we purchased the DVD - cost $19.50
• Somehow the DVD broke, so in a fit I purchased it through iTunes - $14.95
• Lost that hard drive and had no back up - torrents save the day.
My philosophy is pixar has already made their mint on me. This one movie cost my family $71.95, and I'm not about to pay for it again.
