Preorder

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

Your Pre-Order is prioritized (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or dispatch to you — it often never even hits the stock room shelves!

Prelaunch

With Prelaunch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Preorders.

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

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

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

We estimate this will be ready for dispatch to you or collection via Click & Collect on Undetermined
