Postal is the only reasonable way to get goods into Canada unless you are a medium or large business with a good broker contract. All of the couriers charge unreasonable fees to clear your goods through customs. Through postal service it is a moderate flat fee, regardless of the value. The couriers have a sliding scale, and charge according to value on top of number of items.
They show up at your door with a big invoice and hold your goods hostage. Even if you try to clear the goods yourself, which you can do in person at any CBSA office with the right paperwork, they are unreasonable to deal with and often refuse to accept your paperwork timely. It's a racket they've gotten away with far too long, Most goods under $150 get cleared through postal with no fees, not even taxes. With the couriers you are looking at a $50 invoice for the same box.
I would be happy to do paypal "send to friend" if you offer postal or parcel one again. I will also look into wise.com
