Hmm even odder: (updated with breaking news)
Buyer purchased 2 things:
Item from .CA at 3:32
Item from .COM at 3:44
(both were paid for right away)
Email for .COM came at 3:55
Email for .CA came at 4:23
Still no email for .CA - revised, see above
So the $C stuff from .CA is coming slower than stuff from .COM
