I have used the service for several years. I often travel in the US and rent cars. #Autoslash has saved me $100s of dollars ... perhaps more. This year alone, they have already saved me over $600 on one long term rental. They have also helped me immenselly with other questions and concerns I have had about various things related to renting a car, like add-ons (insurance especially) and memberships in other organizations that might discount rentals (like AARP and AAA). YOU MUST USE THIS SERVICE IF YOU RENT CARS, EVER! @Autoslash
