I think I sent payment over the first weekend of March, which would have it being picked up on the first. It's possible I sent it a couple days later (I leave envelopes by my door, and pick them up each morning to mail, although occasionally I forget), but it would not have been delayed more than a couple of days. In your experience, how long does it take mail to reach Canada from the US? I wouldn't be adverse to sending another payment, but would like to know how much longer we should wait.
P.S. Sorry I didn't reply earlier---I normally don't frequent TCC, and only got an email notification of a PM today.
