That's why you always order something very cheap that is definitely in stock along with the main order. A lot of people order a keychain or Xtra poly. I did the Disney Train thing and bought a $20 Duplo set for my granddaughter. I received this from LEGO just an hour later:
We apologize for any inconvenience this delay may cause. If you’re worried your order will not arrive in time and you wish to change or cancel the item(s) below, please contact us at 800-835-4386

When I checked online, it showed that both GWPs, the camera and the Duplo set were all being prepped for shipping and the Disney Train on backorder.
