Unfortunately yes. Our system is fast however, sometimes not fast enough. Out of stocks can occur after your order has been placed. When this occurs a member of our Cheegs team will reach out to you to see if you would like to update the color or size of the item to one that is in stock or if you would like the out of stock item to be canceled and refunded. Only color and size changes can be made for out of stock items, a different style cannot be selected. We apologize for the inconvenience when this occurs.
