Via Points, Miles, and Martinis, Visa Checkout is offering $15 statement credit if you pay with Visa Checkout on various online merchants using your Chase Sapphire or Chase Sapphire Preferred card. Offer is valid once per card, not per merchant unlike the Amex Checkout offer.
There doesn’t seem to be a minimum limit on the purchase amount, but we don’t know yet if you will receive a credit for amounts < $15. But if you buy something really cheap, then the risk might be worth it.
