Maybe I am just missing something but I thought if you pay off the credit card in full before the due date, you don't owe them more money. Is this concept not correct? Both of the Citibank cards have charged me subsequent "interest" payments which are all due in full. I need to take those fuckers on but am just too tired this week. Different hours, different job, different stressors. Ambian is failing me right now.
