When you place an order for an item that is available as a pre-order, it will either be shown on the button when you add the item to cart, under the product in your cart and when checking out, or in the product page in the description section -- or in all of the above-mentioned sections.
We generally specify a timeframe within which shipping will take place. For example, pre-order information may look as follows:
"Shipping between days X and Y of month Z."
or
"Shipping between days X and Y of month Z, if the order is placed on or before day W."
These are timeframes within which the shipments depart from us only, and they do not reflect the transit time, or how long the courier service will take to ship to you. As soon as the package is handed to the courier, we can no longer influence the shipping process in any way, as it is up to the logistics of the courier.
We always strive to deliver within the timeframe indicated, but please note that all shipping dates are estimates only due to the reasons listed above, as well as due to reasons that are reasonably outside of our sphere of control, such as delays we cannot influence.
A pre-order is a purchase agreement/contract that essentially reserves the products you want in the sizes desired, as we operate with limited quantities of stock, and you may exit it at any point if the parameters within which it operates are no longer suitable for you.
