Does anyone have tips on how to maximize credit card benefits? I charge whatever I can, including gas, groceries, hotel stays, and airfare. But is there a way to use credit cards to pay bills and get points? I know some of you have some great methods for maximizing the amount of miles earned on credit cards. Most of my big expenses are still paid by checks or transfer of funds from my checking account. I wish I could charge my mortgage and other bills to get MR points, etc. Is there a way?
