ShopRunner offers PayPal members a ShopRunner 2-Year Membership Trial for free. That yields a saving of $158 and is the best offer we've seen for a ShopRunner membership that didn't require a specific type of credit card.

The membership includes unlimited free 2-day shipping, free shipping on returns, and more. Some of the vendors that use this service include Newegg, NFL Shop, Saks Fifth Avenue, Under Armour, and Eddie Bauer.
