Depending on where the papers were going, it's possible it could take 2 weeks; that's getting to the end of the limit though. I've found the mail sort of goes in cycles; you'll get fast delivery at times, then it becomes very slow, and it doesn't seem to matter which way the mail is going, if it's slow, it's slow to anywhere. There was one week the end of June when I waited 9 days for a letter from Alberta; about that same time I mailed an envelope down to Arkansas & it took 10 days to get there. A couple weeks later I mailed another envelope to Arkansas & it got there in about 1/2 that time. Likewise, in a good week mail comes & goes from here to Alberta, or from Alberta to here, in 4 days. I've had paperwork arrive from AMHR after only 5 days in the mail, and other times it's been a full 2 weeks in the mail. We've had mail take 5 days to get from Winnipeg to Brandon, and that's only a 2 hour drive. :new_shocked:
I'd be inclined to wait 3 weeks & then send for duplicate papers. I guess the buyer won't like it, but if they're lost in the mail there's not much else you can do.
