After a long time, ZipZap got back to me and said the payment is stuck in MG. I've verified all the info was entered correctly on the form by me, so it's possible the clerk maybe mistyped something in...

But my questions are -

1. If I cancel and redo the ZipZap payment, after ZipZap notifies your system, will BitInstant still pick it up and send the funds to my bitcoin address?... Because it's now going to be 12-24h after the initial quote was made, and your public transfer-to-address function is down.

2. At what point am I locked into the USD-to-Bitcoin exchange rate? At BitInstant quote time, at ZipZap notification time, or at Exchange execution time?
