A more sweeter deal is to get $50 OFF using code DISCOVER50 and pay with discover card. Look for silvercar under discover deals to avail this.
This is a great opportunity to get away at a discounted price -- especially during the summer, a peak travel time. Silvercar is a nice alternative to the traditional rental car agencies, as it offers a fleet of new(ish) Audi A4s. Each car comes with Wi-Fi, GPS, Bluetooth and Sirius Radio. If you choose to take advantage of this discount, be sure to reserve your car with a credit card that offers primary rental car coverage, such as the Chase Sapphire Preferred.
