Occasionally we may in peak periods sell out of an item due to popularity that you'll be able to place orders for and reserve one from out new stock arriving. When an item is available to pre-order, we'll show you an estimated delivery date on the item product page.
We have new stock on order all of the time but is difficult to determine how quickly an item may sell and could sell out before the new stock arrives this is why we are now offering our customers to place a pre-order to reserve an item on new stock.
If you order anything else with your pre-ordered item, it'll only be sent to you when your pre-ordered item is available. You may want to place a separate order if you want your other items sooner.
