Costco Members – Free $20 Costco Cash Card for existing members, if you sign up for auto renewal – YMMV

Got a flyer in mail today, receive FREE $20 Costco Cash Card when you sign up for auto renewal on any Visa credit card by January 31, 2019.
Letter says: You also can sign up at the membership counter of your local Costco. Take this letter with you and enroll by January 31, 2019.
Not sure if this is targeted so YMMV. Looks like may not be targeted but Offer is Valid for new auto renewal enrollments only.
