3. Fees for paper statements
Some credit cards now charge $1 each statement period if you want a statement snail-mailed to you, rather than emailed.
So why not go green and opt for online-only statements? Make sure to save each month's statement on your computer so you have a digital "file cabinet" in case you ever need to consult an old bill.
One cautionary note: When you're first making the transition from paper to digital, you may miss the visual trigger you used to get from the bill, and that could lead to a late or missed payment. Also, if the card issuer's email fails to reach you or winds up in your junk folder, it's still your responsibility to pay on time, says Linda Sherry, spokeswoman for advocacy group Consumer Action.
