In the event that he can't, you may wish to consider a Kinek depot in Buffalo or other border city. Free to get an account you need only visit http://www.kinek.com and do a search for the nearest spot. You will now have a US address so just think of all of the free shipping deals on eBay, et al you can take advantage of.

The going price is $5 US or $6 Cdn for each and every parcel you pick up depending on size of the container. I've never paid more than that for anything including two tires strapped together (yes, four tires cost me $10). As well, I have used this service for more than five years now (near Kingston) and love it.
