Pre-order means that the product is not currently in stock and you must place your order as per normal if you'd like to secure your size before the item arrives with us.
You will proceed through the check out as usual & make full payment when making a Pre-order. Your order will only be shipped upon arrival of the ordered Pre-Order item/s, usually as per the date suggested on the product page at the time of order placement. And we will update you when your items are available for shipping.
For any questions, please contact us at email@example.com.
