Watch Battery

I don't know what to say. The battery is for a watch. The watch runs.
  • The battery price was very good.
  • I just ordered three batteries. They are very small. It seems to me that the batteries could have been put in an ordinary envelope with one first class stamp and mailed to me. The $3.50 shipping charge seems a bit of an over-kill.
