Yeah, it is hit-and-miss, which is sort of maddening because you don't know what's going to make it and what's not. I send 2 cards to different parts of England and one arrived 5 days later and the other has yet to arrive (20 days later). I sent 4 cards to 4 different places in the US and, as far as I know, only 1 has arrived. *shrugs*
