Jordan, I`ve grown accustomed to paying the Canada Post TPS and TVQ (Tax sur produits et services and tax des ventes du Québec). Admittedly, they are not always consistent. Sometimes they stick it in the little box at the subdivision mailboxes and put the key in my box.
I too avoid Purolator, UPS, FedEx, DHL, etc. to avoid the brokerage fees. ESPECIALLY UPS!
I notice that if there is an invoice on the outside of the box, they usually want to be paid. If not, they let it go by. Maybe there is something about how it`s shipped.
