This is one of the most poorly designed apps I have ever used. It logs me out of my account several times every day. When the one shoe I was looking to buy was released after 5 delays I was unable to check out despite having all my information saved and ready to go. The purchase button remained greyed out until I re-added the address that was already there and then it produced an error when I attempted to purchase until the shoe was sold out. What a waste of a month and a half.
