Apple Pay is a quick and easy checkout solution for customers using Apple products. You can use Apple pay while using any Apple device by clicking the "Apple Pay" button on cart or checkout pages.
Look for this button on your cart or checkout page:
Once you click the Apple Pay button a box will display for you to choose your shipping information. If you are on a desktop or laptop you will then need to confirm payment on your iPhone or Apple Watch with Touch ID or Face ID. That's it, a quick and easy way for you to check out every time while on your Apple device.
