Chase Sapphire: Get $15 When You Pay with Visa Checkout
Through September 30, 2015, Chase Sapphire and Chase Sapphire Preferred Visa credit cardholders can receive a one-time $15 statement credit when they pay with Visa Checkout.
Your purchase may be made at any store where you see the Visa Checkout button at checkout, which includes a long list of online merchants, such as Staples, Gap, Pizza Hut, Neiman Marcus, Newegg, Gymboree and many more. The terms also do not specify a minimum purchase amount, so presumably any purchase should qualify for the $15 credit.
Terms of the offer are as follows:
To qualify for this offer, you must use your Chase Sapphire or Chase Sapphire Preferred Visa credit card with your Visa Checkout account during checkout. Limit (1) $15 statement credit per customer or card account. Allow 1 to 2 billing cycles from Visa Checkout purchase for delivery of the statement credit to the Chase Sapphire account added to the Visa Checkout account; your card account must remain open and not be in default to receive the statement credit. Statement credit cannot be processed if your card number expires or changes while statement credit is pending. Statement credit will appear on your statement as a stand-alone transaction independent of any purchase transaction. Chase or Visa may terminate this offer at any time without notice. The value of this reward may constitute taxable income to you. You may be issued an Internal Revenue Service Form 1099 (or other appropriate form) that reflects the value of such reward. Please consult your tax advisor, as neither Chase, its affiliates, nor their employees provide tax advice.
