    With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

    You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


    With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

    So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    Estimated Delivery Dates

    Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

    The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.


    Thanks for choosing his item ...
