Over our minutes!

Pet peeves....both Kelli and I have them. One of mine is using the home phone when at home. Simply eh ? Kelli thinks otherwise and uses her cell phone 90% of the time. I am always fearful we would go over our minutes on our cell phones. We only have 500. We signed the contract over two years ago and it's worked fine. We get unlimited nights+weekends+mobile to mobile. Well this month we Kelli went over. Thankfully we only have until Friday for our minutes to reset. As of right now I have used 168 minutes....Kelli has used 345 minutes not including nights, weekends or mobile to mobile. Yeah. Gotta work on that. The 500 minutes cap is normally just enough. We normally have an hour or maybe a little more to spare each month. I know I don't pay the bill....but I am trying to save as much money as possible!
