Sorry for the off-topic nature of this post (admin can delete if they want to). I found it interesting that my Avril Lavigne signed art card order was sent from the UK to Addison, IL where B2C Europe probably has a distribution plant... After it arrived to IL it was sent to me using the US Postal Service INSTEAD of Royal/Air Mail! My order had gone through International and Domestic shipping.
That's because someone crossed out your name and address. Royal Air Mail had to ask USPS to find you and deliver it.
