I was just browsing my offers available on my Paypal account and I noticed that they were offering a free 1 year subscription to Shoprunner. 2 day free shipping from a large number of retailers. For us gaming folks, we'd probably mainly use Newegg for this
Head over to Paypal.com log into your account, click on the benefits/offers then see offers and you should have an offer a FREE one-year subscription to ShopRunner ($79 value). All of the options are towards the top right of the page.
Sounds like it also requires a new Shoprunner account/e-mail. You cannot use your current account to get another year added onto your current subscription.
As others have posted. This does not appear to set-up an auto-renewal for next year on your Shoprunner account. Check your own personal Shoprunner account for details but it doesn't have any Credit Card or Paypal information imported in or anything on my own account.
