Have you ever used Shop Runner? I signed up for a free 1 year membership last year and love it. You get free 2 day shipping on qualifying items through many online stores, like Toys R Us and Drugstore.com. It's great to not have to worry about meeting the free shipping requirement and you it in 2 days!
Right now through Cozi, you can get Shop Runner free! Go here to register for a free 6 month subscription to Shop Runner. It takes about a minute to sign up and you are set. You don't even need to enter a credit card number, so you won't be charged at the end of the 6 months unless you decide to continue your membership and enter you payment info.
(Thanks, Mojo Savings!)
