Expedia's lost its way. They now allow scam car rental companies to include buried small print (have to read the small print, then click through links to see this...) that seems to authorize companies like Economy (DBA JET CAR) to extort unsuspecting expedia customers (who have been quoted a rental price that state "No surprises! All fees and taxes included") for crazy fees at the time that they come to pick up their vehicle. In this case, an "insurance transfer fee" to be able to charge clients who have insurance for their rental (either with their credit card company, car insurance policy or both).
Expedia knows about this and does nothing but defend such obscure, under-handed measures. Shame on you Expedia!
