A lot of the smaller repairs like screws, tape & such I can go to the hardware store around the corner & buy it. The sales people fix it before I leave the store.
For the larger repairs, I'm in the same boat as yall. Although, I do buy smaller items like my Roho Cushion. I want to get an arm that includes a place for my hand to be strapped in. That item I will have to order myself & send the bill to the insurance company.
