Free Shoprunner membership

Shoprunner is a great membership service that gives you free 2-day shipping at a variety of online stores, including Drugstore.com, Newegg, Shoes.com, and many more. Until the end of the year, they are giving away free memberships to American Express Platinum cardmembers when signing up at this website and using code "RUNNER". This means you get free returns and (near) instant gratification at a variety of stores, just in time for the holidays.
