Did you pay extra to have it delivered to your door?
My husband registered for his interview date and then the "choosing a courier" part was only choosing a generic location for DX (so he picked London as the best option of the 3 choices... the others were Manchester & maybe ireland?). Anyway, It didn't even ask him for his address to send the documents to so we assume it's going to go to some London DX Courier depot and he has to go to London to pick it up from DX.(?)
All this to ask, did you have similar courier options and did it come directly to your door or did you have to pick it up from DX?
