I had a problem with movies. I couldn't go into any store without leaving with a handful of movies at full price. That's about $20 per DVD and $30 for blu-rays. I'd spend $100 at a time and walk away with 3 or 4 movies. Now I get my movies on half.com and wait about 2 months after the movies release. Now I buy 6 to 8 movies, mostly Blu-rays, for under $50. In addition, it takes me a few weeks to go through that many movies so i end up buying only about every 3 weeks or once a month instead of every week.
Lastly, I can go into Best Buy and instead of buying a handful of movies, I cringe at the ridiculous prices and just walk away.
