At this time, ToysRUs is unable to modify or make changes to an order once it has been submitted.
Only Ship to Home orders with Economy or Standard Shipping may be cancelled within 45 minutes of submitting your order. All other orders, including Ship to Home orders with Express or Expedited Shipping cannot be cancelled after the order is submitted because they are processed immediately to ensure ToysRUs meet the expected delivery obligation.
If you are able to cancel your order you will see a "cancel order" button when viewing your order in the "track your order" section of the website (My Account -> Order Status/Tracking -> Track your order). You can also access your order by clicking on the link found in the cancellation information section of your confirmation email. When viewing your order simply click on the button and your order will be cancelled. If you do not see this button, that is an indication that your order is either not eligible for cancellation or it is too far along in processing to be cancelled; it will ship as expected.
