MasterPark offers numerous SeaTac Airport valet parking coupons on its official website. Coupons may provide daily, weekly or monthly savings as of 2015, notes MasterPark.
Customers cannot combine the savings from an online coupon with any other discounts, states MasterPark. Other fees, such as state sales taxes, city taxes, living wage surcharges and airport access fees, still apply to the purchase. All coupons must be used before their expiration dates.
To receive a coupon, provide an email address in the Web Coupons section of MasterPark's website. Print the desired coupon and present it to a cashier to redeem its savings. MasterPark offers customers the option to receive future discounts through email as of 2015.
