I have also heard that for those of us that pay off our balance every month so we have no interest will now be charged interest from the day of the charge. So far that hasn't happened but I am certainly watching our account.
Also, we bought some furniture with 3 years no interest. We have the money in the bank but I thought I would let it draw interest for 3 years. We received a notice they will be changing our agreement. Needless to say I paid it off. I don't trust the credit card companies.
Best Buy almost always holds your payments so you have late fees. My husband calls is "Worst Buy"
