I'm sure the GM card charges a higher interest rate on unpaid balances to permit them to give you the 5%. There are no free lunches in the credit card business.
i always pay my card off each month. had it for 26 years and never had a balance go over a month.they actually dont like me, they want people that dont pay there cards off each month. i am up to 21,000 on my credit limit and they still cant trap me on not paying off each month, ha ha.
