Hello. I ship mostly to the United States and use Canada Post Small Parcel to the U.S. Usually it costs either $3.95 or $5.75 shipping. I am concerned about my items getting to the States in time for Christmas.  Any opinions on what deadline I should use?  Also, what experience have you had with U.S. expedited parcel?  Is there a flat rate like there is with small parcel?  Do some of you stop selling at a certain date before Christmas?  Is there some sort of notification you put on your listings?  All advice welcome.
Cherie.
