You'll get free two-day shipping on purchases and free returns at partner retailers simply by checking out using the ShopRunner link on the retailer's website. To access ShopRunner perks, you'll need to select ShopRunner checkout, sign into your ShopRunner account, and confirm your shipping information and payment details. If you shop online often, you may decide paying the fee is worth it — or you can sign up for a credit card that provides a free ShopRunner membership as a perk.
