Happy birthday Dan, now go out there and save $6.

Today is my birthday, and I decided to treat myself by buying a protective case for my Kindle.  I researched cases and found a good one based on reviews.  I was able to locate it on ebay for $18.  Thinking I got a good deal, I bought it, but then I made the mistake of looking on amazon.com.  I found it there for $12.  I was steamed I payed too much for this cover, but then I got to thinking about it.  Will my life really come down to having an extra six dollars?  Probably not.  Why do we become obsessed with finding the lowest price?  I think it has to do with being able to feel like you got the best of the seller.  What a way to start off 32.
