Was the company name Pitney Bowes?
That's the international company that runs the GSP.
The $2.45 goes to the shipper who will buy USPS (usually) shipping to the GSP plant in Erlanger KY.
Then PB/GSP uses the $13.29 to pay applicable Canadian duty and Sales Taxes (usually its mostly tax) and takes a service charge of ~$5USD for their work in wrangling the purchase across the border.
Actual delivery will probably be by Canada Post.
So no worries.
BTW- once it is at the plant, tracking becomes difficult but it should reliably get to you within the next three weeks or less.
