Hidden Fees in Banking and Credit Cards Explained

Banks and cards hide fees in "convenience" charges, costing average users $100s yearly. Balance transfers: 3-5% (Bankrate/National Debt Relief)--a $5K move hits $150-250 upfront. Cash advances: 3-5% + $10 flat, treated as loans. Annual fees divide experts: Bankrate says rewards justify them ("exponentially more value"), but opt for no-fee if unused.
