I think the problem has gotten better. We used to do a survey, and we found that it was less expensive for a Canadian seller to drive something across the border, put it in the mail in the U.S., and then have it sent back into Canada. In 2013, USPS increased its rates significantly on international shipments, and that problem seems to be less of a problem now.
When you heard from Maureen, she wasn't driving her Canadian inventory across the border to induct it into USPS in order to send it back into Canada. I would say that was probably less of an issue, particularly relative to the U.S., than it had been previously. But on the specifics right now, again, I don't have that information.
