I just signed up with my Club Carlson credit card and found that pretty easy. Now I just have to find a place that accepts Visa Checkout.
Here are the T&Cs:

The $15 statement credit will be awarded upon verification that you (1) create a new Visa Checkout account through mycard.usbank.com/15visacheckout during the offer period and (2) enroll your eligible U.S. Bank Visa Consumer or Business credit card in a new Visa Checkout during the offer period. The $15 statement credit will be applied to your account 10-12 weeks after the end of the Offer Period. Limit one statement credit per person. Statement credit to be paid to the first U.S. Bank card enrolled in a new Visa Checkout account. Your account must remain open and in good standing to qualify.
