I would love if Sunpass and E-Z-Pass got their code traded so one device could be used for both. Until then, Walgreens and Publix all carry the Sunpass in FL. The window sticker kind is 5 bucks.
Well, Florida just consolidated their own passes just a couple of years back. We had had SunPass, E-Pass and the Orlando area had the O-Pass as well. I was concerned that SunPass won out (politics), as the E-Pass was a built on much better technology.
