Hello!
Just passing through while looking for posts on holiday mail issues (specifically the 9th & 12th... ughhhhh!)
I too have noticed a decrease in numbers since this feature began, and while many issues could be responsible, I do feel it has had some effect.
Many US buyers, for various reasons, are nervous to buy an item from Canada, and this new addition only increases the chances they won't even look to start with (and that probably applies somewhat to buyers/sellers from other countries also).
I can make a guess as to why it was implemented, but ultimately, I think it will hurt good sellers everywhere, and limit buying overall, not increase it.
Just my 2 cents anyway. 🙂
Happy New Year to all!
