I did a search and did not find this deal posted before. I just got an email through my AAdvantage card indicating that Citicards now offers free complimentary ShopRunner membership to Citi World and World Elite Mastercard cardholders. This appears to be a perpetual ShopRunner membership as long as you have the underlying card (similar to the Amex complimentary membership).
For those who are not aware, the ShopRunner service gets you free 2-day shipping and free return shipping at participating stores. A list of the participating stores is available here:
The enrollment page is available here:
The fine print:
*To get the free ShopRunner membership benefit compliments of Citibank and Mastercard, you must go to www.shoprunner.com/mastercard
to sign up for a ShopRunner membership account ("ShopRunner account") with a Citibank World Mastercard or a Citibank World Elite Mastercard. ShopRunner will verify the eligibility of your credit card account number at the time of enrollment. To maintain your ShopRunner membership, your eligible Citibank Mastercard must be linked to your Shoprunner account or the membership may be canceled.
You can maintain only one ShopRunner account per eligible Card. If you currently have a free or promotional membership on your ShopRunner account, you should consider whether to enroll in the benefit at this time. Please visit https://www.shoprunner.com/terms/sr/
or contact ShopRunner Member Services at 1.888.721.7467 (SHOP) for more information. For details on how the ShopRunner membership works, please see the ShopRunner Terms and Conditions at https://www.shoprunner.com/terms/sr/
