I came across an article about this interesting business...
Many US companies won't ship to Canada, or they charge a large shipping fee. So what some enterprising Americans who live near the Canadian border do is provide a "parcel pickup" service.
That is, they let Canadians use their US address (for a fee) as the address to ship their products they've bought online from US online stores. Then, the customer can drive across the border from Canada to the US to pick up their parcel at their convenience. While there is a little bit of extra inconvenience for them, it means that Canadian customers can save money overall by using these services.

By the way, I've written about a more sophisticated, yet in some ways similar (in the kind of service it provides), type of business which provides a service to Australians who want to buy from the US... You can read more about that here...!

There is a problem here to be solved, and money can be made by helping to solve the problem!
