Free Shoprunner one-year membership or renewal

Get a free new membership or (for current members) one-year renewal Shoprunner membership when you click here and attach your American Express card to your Shoprunner account.  As long as your Shoprunner account is NOT set to auto-renew after the promotional year is up, they will not automatically charge your American Express card for any membership fees without your expressed approval.

For those of you who are unfamiliar with Shoprunner, it's a paid service ($79 per year) that gives you free 2-day shipping with no minimum purchase at select online vendors.  I've been a member of Shoprunner for three years now, and have never paid a dime for membership.  As long as they keep rolling out the deals, I'll bite.
