Be wary of renting from Thrify in Seattle.
If you do not pay for their electronic toll payment option at over $10 per day and travel over the evergreen bridge you will certainly receive a $15 charge, plus the cost of the toll for each transit. You cannot pay cash at the bridge. You cannot contact the toll authority web site or toll free number and pay with a credit card for a car registered to the rental company. That's the way the process works. Once you go over the bridge without the electronic toll box, you are on the hook to Thrift!.
Thrifty, for their part, will not accept responsibility for informing consumers of this situation. Their position is that they offer you the box and if you decline, that's your problem. We did not know that there was no cash option at the bridge when we reserved the car or when we picked it up. We did inform thrifty at the rental counter upon return that we owed a toll and wanted to pay. The agent gave us a piece of paper with a website and a tollfree number to call, with process instructions. We called that number and attempted to make payment. We told the agent the license plate for the car and the time of the bridge transit. We were told that the payment would be processed. 4 months later, Thrifty billed my credit card for the tolls plus a $15 administrative fee. I offered to pay the toll. They will not waive the administrative fees. They do not make exceptions. Neither do I.
Goodbye Thrifty. I simply do not do business with a company that insists on profiting from it's customer's failure.
