And they may be so buried in the fine print you've never heard of them.
Pew’s mission is to convince all banks to include for all checking accounts disclosure boxes similar, yet considerably longer, to those now found on credit-card bills. But through its annual Safe Checking study it has uncovered a number of items and fees that most consumers wouldn’t have a clue about until they got hit with them.
These include crazy things like a fee for returned mail if you moved, a fee for closing your account too soon, a fee for sliding an empty envelope into the ATM deposit slot, a return deposit fee (because the check you received wasn’t good – how are you supposed to know that?), an inactivity fee, and a fee for depositing too much money. They can range from $3 to $35 each.
