"Book orders" joke

I have a friend whose job is to process book orders that people have placed by mail. Sometimes, the books ordered tell a whole story in and of themselves. Here are three that caused quite the laughs:
One order for two books:
1. "How to win every argument"
2. "Conversations with God"
Another order:
"For My Only True Love"
Note - please send three copies
Last order for four books:
"Getting along with mean people"
"How not to be mean"
"How to stay lovers for life" - two copies please
