I just saved $100 on my car rental thanks to my credit card. I researched many discount travel websites, all quoting me at about $340 for a 5 day rental from Glacier International Airport. At the last moment before I booked one of the offers, I remembered that I should check the Chase Ultimate Rewards to see if I would get additional points for booking through their site. When I ran the query for the same dates, times and economy car, I was ecstatic to see the price was significantly cheaper at $225 for the exact same car from the exact same rental agency (Alamo). This is the first time I cashed in on a perk for having the Chase Sapphire Preferred card. After this deal, I won’t forget to check Chase’s Rewards Mall again!
