The prices we're showing on the site are the all-in daily rates. So if the price for an Explorer is $65/day and you rent it for 2 days, you'll be charged $130. Whereas when I look at Hertz, the price for renting a standard SUV for their downtown location from the 28th to the 30th is $140 per day, but for two days the total all in cost is $320 without any extra add-ons.
It might actually make sense for us to show the prices on our site without taxes+fees included so as to look comparable with other companies' prices.
