Be cheaper than cheap!?

My wife has switched her smartphone to another company this time. It was a new model, so I was prepared for a high price, but it was almost free.
I can not understand this mechanism at all. However, I am glad that it was cheap.

Sports disorder?

Today, I happend to meet a friend's wife at the hospital's waiting room.

She released various topics about the members of tennis club I belonged to before. To my surprise, many of the members at the time are suffering from health problems, many of them are foot and back pain.
I believe that tennis is a healthy sport, but I can not win over my age.
