Charges are not the same from month to month.

[Kathlyn14]

In the last 3 months, my charges have changed. It's really small but I'm just curious as to why it isn't the same from month to month. This past month it was $10.66 after tax and the month before that it was $10.81 after tax. Is this happening to anyone else? Does anyone know why it changes?

Could it be because taxes have risen in your area?
