I personally do not use my credit cards much for purchases. I think they are vultures who are allowed usurious rates that would be considered loan sharking if anyone else did it. That said here is how I make money from my credit cards: Balance Transfers
I always get the 0% for x months and the 2.99% offers. So this is what I do.
I take out transfers on then and open CDs and momenymarket funds with the money. Lots of CDs are paying between 4.75 and 5.01% for the year and some have 3-12months CDs.
Last year in interest I racked up almost $3,000 and the cost to me to do that was less than $200 (some cards charge a BT fee).
I am now working on establishing reported business credit so I can get business cards and lines of credit so I have more money to play with
