Toys"R"Us presently provides a flat rate simple shipping structure based on the number of items you purchase, whereby products are shipped according to their weight or size only. During checkout a number of delivery options will be made available to you depending on how our system categorises the final expected carton, plus your delivery location. For example if you are overseas, you will have a number of options made available depending on order value, weight and size - including express delivery options. Within Australia you shall have a number of options also, with an estimate of delivery timeframe - including same day delivery options depending on your location.

That are large or heavy can only be transported using road freight methods and sometimes attract a higher expense depending on location. This will be therefore be indicated during checkout.For more information, visit our Shipping Policy page.

At Toys"R"Us we'd like you to know that we are here to help you if something goes wrong with a product that you purchase from us. In order to assist you to ensure everything goes smoothly with your purchase and delivery, please be certain to:

• Step 1: As soon as your package arrives, check that the correct items have been sent to you. Whilst we have multiple checks as we prepare your shipment, unintentional human errors can occur and the best time to verify everything is perfect is as soon as you receive your delivery. Check the cartons carefully as parts or small items can sometimes move around and easily be caught inside packaging or void-fill.
• Step 2: Do not throw away any of the original packaging materials, such as boxes, instructions, inserts, bags etc. until you are satisfied with your order. If a problem arises it is normally much easier to resolve if everything is together - there's nothing worse than contacting us regarding a missing part and learning that it is carefully protected inside the foam protector, on its way to land fill in your local municipality because it was accidentally disarded.
• Step 3: Carefully inspect all merchandise, taking care not to damage packaging.
• Step 4: Please keep the supplied Toys"R"Us invoice or packing slip / invoice slip with your important records. This helps us to more easily track the history of your purchase. If a problem occurs you can refer back to this information (or the order reference information that we email to you) to quickly enable us to understand which product you are referring to when you need assistance from us.
• Step 5: Enjoy your new product!
