Mobility Scooter (Citra, Fl)

looking for a mobility scooter. I have arthritis in my knees and legs, I have problems of getting around because I have to stop every 10 or so minutes to rest, Also I dont drive a car. My insurance tells me the only way they will help me out with a scooter is if I need to go from my bed to my bathroom or kitchen, but I also need to get to my mail box 3/4 mile away, or a store (1 mile away).. If you can please help
