Don’t junk your monthly statement! One of those loose flyers inside Hilton’s U.S. mailing received in November is a coupon for a free one day rental from Avis. Simply present the coupon at any Avis location in the U.S. or Canada between Nov. 1 and Feb. 28, and get a free day on your next intermediate through full-size four-door car rental of four or more days, including a Saturday night. Be sure to mention coupon #TUHA004 when making your advance reservation.
