I use these guys. It is just on the other side of the 176 St border crossing.

That border is only 20 minutes from where I live, and usually mid week, early afternoon, lineups are pretty small. So I use it quite a lot. I rarely get charged tax at the Cdn border, only sometimes for large amounts, like 1K.
Cost is $3 a parcel. When ordering online, I just use my name with their street address for the shipping address. Then I watch the tracking online for when it arrives. Pretty painless.
