I've never seen someone admit that, but it doesn't surprise me. I'm a lover of "B" movies, so I've been buying "crap" since DVD days. But I never buy anything that I don't want to watch, even if it's only a dollar.

Never saw any logic in buying something just to artificially create a number or a pedigree, like the people that only buy foreign movies to make themselves look cultured, or a vast library of books to look smart.
No, not low, you just have to be patient and watch this forum. It's all YMMV of course, depending on the type of films you like. I buy a little bit of almost everything, love expensive Criterions and all the new blu-rays, but also buy lots of classic film packs at a couple bucks a movie, and direct to video horror titles for $1.50 used. So it all balances out to about $3 a film DVD, and $8 BD. Someone who didn't buy Criterions would be much lower, someone who only bought Criterions much higher. But except for these, I rarely pay more than $10 for a blu-ray, pretty much every release has been that price or less if you're patient and vigilent.
Really? I'd say the exact opposite. I've found almost everything I own in the past year cheaper than when I first bought it. This is by far the golden age of DVD (and BD) bargain hunting imo.
Exactly. A good chunk of my higher end BDs (Disneys) have cost me $5 or even less than zero. It's all about timing and reading.
