If you’re seeing an error pop up preventing you from adding an item to your cart, double-check your cart! The error occurs when you attempt to add an in-stock item to your cart alongside a pre-order item.
To order a pre-order item, it must be the only item in your cart. You may order more than one of that pre-order item in the same order.
To order an in-stock item, add it to your cart while the pre-order item is not in your cart.
