I received the same Amazon.com email on 7/3, telling me that I am now eligible to Shop with Points at Amazon.com. Sure, it is nice we have an option to unenroll on the amazon.com website, however there should be something on Citi's website that allows credit card holders to not enroll to link Shop with Points for any partner! In June, I received a similar email telling me my Citi ThankYou points were linked with Paypal. This is really annoying. How can one choose to not allow Citi partners to automatically enroll ThankYou cardholders for Shop With Points? It would be nice to know what setting can we select on the Citi website or tell Citi's customer service so this doesn't happen again for any Citi partner.
