Everyone loves getting something for free, but retirees may be overlooking an even better deal: services they are already entitled to use because they are paying for them somewhere else. Insurance premiums, credit cards, memberships, bank accounts, government programs, and other products can include benefits that are easy to forget or never discover in the first place. Paying another company for the same service can quietly turn a $10 or $20 monthly expense into hundreds of unnecessary dollars over several years. The catch is that benefits vary considerably by plan, provider, location, and account, so retirees should verify coverage instead of assuming something is included. These seven services retirees may already be paying for are worth checking before pulling out a credit card again.
