I was going to rent from Hertz this weekend so after I called to change my flight today I asked to be transfered to Hertz.
Their first quote was about 7.00 more a day then I was quoted on their website (I was told this was a "35%" discount). After I asked "is that really the lowest price?" they gave me a qote that was about a dollar more a day than their website. I thanked them, hung up and booked on the website.
Probably the last time I'll ask to be transfered.
