In fact, as a reassurance, I'd like you to send first. I have had multiple previous, successful, trades. Just send one, then I'll send the yellowbird, then you send the other 2, okay?
Nope, the Yellowbird has been sent. I went Offline so that it doesn't stop me from sending any more cars; if you turn off after it saves, rather than clicking OK, it doesn't count towards the 1-car-per-day Limit.
You should have the CTR in your possession by now?
