This app is as bad as Nike’s customer service. The app doesn’t send notifications when it’s meant to or reserve items added to the cart, so chances are your item will disappear before you complete the checkout process. Even if you successfully purchase something, Nike may cancel the order 12 hours later because they have oversold stock. I have sent plenty of feedback to Nike, but they don’t care about their customers. I would buy all of my Nike gear through other retailers if I could.
