but how do i know if i'm i'm getting a good deal? i tell truecar my zip and which car i want and truecar shows the range of prices people in my area actually paid for the same car so i know if i'm getting a great price. this is how car buying was always meant to be. this is truecar. gimme two minutes. eligible for medicare. and i'll tell you some important things to know about medicare. first, it doesn't pay for everything. say this pizza... [mmm pizza...] is your part b medical expenses. this much - about 80 percent... medicare will pay for. what's left... this slice here... well... that's on you. and that's where an aarp medicare supplement insurance plan, insured by unitedhealthcare insurance company comes in. this type of plan helps pay some of what medicare doesn't. and these are the only plans to carry the aarp endorsement. that's because they meet their high standards of quality and service.
