I did a quick google on Forida Turnpike and I got all sorts or info. Apparently as of Feb all tolls are collected by Sunpass. On a plate photo basis. They bill you for a 30 day period to the owners of the vehicle. The area involved is from rout 1 to exit 47.
If you were charged 103 dollars they are either trying to nail you with all of the tolls that car has incurred in the last 30 days or you are paying by the foot. It is pretty funny that by not having to stop at a booth you get the priviledge of paying .25 cents more for each section.
They show a cumulative cost from exit to exit, and I don't know how long you were on the pike.
I know the Mass Pike from NY line to 495 is only 2.10 but the NY thruway is 15.55 from Buffalo to the Mass pike. About 300 miles.
So even with the 2.50 statement fee, you probably should have paid about 20 bucks round trip.
Check it out. If you scroll though the whole thing you get a map as well with a breakdown of charges.

On further review I see that you can get a transponder and it is a lot cheaper.

All Turnpike tolls are now collected electronically between the U.S. 1 (Exit 1) and County Line Road (Exit 47) interchanges in Miami-Dade County; no cash or credit cards are accepted. Motorists must use either SunPass or TOLL-BY-PLATE, and everyone will have the benefit of paying tolls without having to stop.
For customers without SunPass, the alternative is TOLL-BY-PLATE, a collection system that takes a photo of a vehicle’s license plate as it travels under tolling equipment installed overhead and mails a bill for the tolls incurred over a 30-day period, plus a $2.50 administrative charge per invoice, to the registered owner of the vehicle.
For those traveling in a rental vehicle, there is an easy and convenient way to pay tolls without stopping. Most rental car companies have programs that allow their customers to charge the tolls to the credit card being used to rent the vehicle. Motorists should check with their rental car company for details. For information about participating rental car companies, go to
