"Unfortunately, your order with Nordstrom has been cancelled because the following items are restricted by Customs."

I wavered on this coat throughout the sale, watched it go out of stock then come back in, called around to Canadian stores for it and finally bit the bullet and ordered it online from the US - only to get this email about it this morning. Darn it! Just when I was getting really excited about it.

So the question is, why would a coat be restricted by Customs when I can order
just about any other item of clothing?
