Pre-Order Information
Items where the “Add to Cart” button is replaced with “Pre-Order” are classified as pre-order items. When placing a pre-order, a warning box will appear outlining the terms and conditions, including the estimated delivery timeframe.
Please keep the following in mind:
Stock is not on hand – we have no control over delivery times until the stock arrives.
Patience is required – pre-ordering secures your item, but fulfilment depends on supplier availability.
High-demand items – pre-orders are the best way to lock in popular products, which often sell out before they even land.
Allow a buffer – please add 2–3 weeks to the provided ETA to account for any unforeseen delays beyond our control.
Pre-ordering ensures you don’t miss out on in-demand products, and we’ll keep you updated as soon as your order is ready to ship.
