Cell Phone Bill Reduction

We have a "family" cell phone plan that allows rollover minutes. We have 3 phones that are all linked together so we only receive one bill. I hardly use my phone and my wife does not use her phone very often. The majority of the use comes from my sons texting. As a result we never use all of our allowed minutes. A quick change on the cell phone providers website and poof, we are now saving an extra $10.00 per month. This savings will go right into our snowflake account.
