Well we bought a Sun Pass at the local Publix and filled it with $10 on line. Also signed up for the auto renewal of $10.00. Good thing! DW decided to see Sanibel Island, no problem. When nearing the tool booth I saw the sign $6.00 per vehicle!!!!!! That just chewed that SunPass into pieces. Auto renew kicked in and we've been good. Been on and off the island more times than I can count. SunPass is worth the money to me!
