Christmas is now exactly a week away and every business and retailer is trying to get as many deals as possible to bring people to their websites and stores. This week’s Apple Pay deal has to do with Nike, more so specifically, Nike’s iOS app.

For this deal, all you have to do is make a purchase of $100 or more in their app and then pay with Apple Pay at the checkout. Afterwards, you will get a promo code for $20 in the Nike store, which can be used on anything in the store. It will essentially be a free $20 gift card or store credit.

The deal starts now and will only be going until December 22, 2018, so you will have to be fast in order to take advantage of this promotion from both Apple and Nike.

Other apps that Apple is promoting this week are their own, the Apple Store, Crate and Barrel and the Macy’s app because they all accept Apple Pay in them. On top of that, Apple is also promoting the ChangeUp app, which allows you to donate to over 800,000 charities with Apple Pay.

The terms and conditions of the Apple Pay + Nike deal can be found below:

*Offer valid from December 16 through 22 on purchases of $100 or more made in the Nike app with Apple Pay.
