It just seems $18.55 is over priced for one adapter. You have about $40.00 invested in adapters including shipping even before you buy the mirrows. Maybe someone else will come out with a more reasonable priced adapter. I know all chrome parts are overpriced so I have started getting some stock parts chromed. I started with the rear footpeg brackets which only cost me $20.00. I had already purchased the chrome footpeg adapters so now I need to buy a pair of chrome footpegs.
