I always found the "Amazon 4-Star" name funny. Presumably when it was first pitched internally it was called "Amazon 5-Star", then they realised that meant they basically couldn't sell anything, since nothing popular gets a full 5 stars. So they changed it to "4-Star", which just sounds awkward, and lacks the suggestion of top-quality that "5-Star" would. Instead, it's like the "Amazon Not-too-bad" store. I was amazed that they actually went ahead with it.
