Almost got it there, but please allow me to clarify.
For each case, and mind you it was a small proportion of the many orders I've placed with Amazon, I first asked for a replacement, and if that one exhibited the same problem (a couple did) or a different one, I only then asked for a refund.
My friends and family would be happy to tell you that I wasn't hosting any superbowl parties with big TVs that I would then return, or taking massive loads of pictures on a "rental camera." I was honestly upset there were issues with these purchases, and followed my rights in asking for an exchange, then a refund.
I totally get the "some people try to get things for free" issue, and realize Amazon must do everything it can to protect themselves from fraud.
I, however, intended no -- and commited no -- fraud.
