Things They Should Invent: don't say no, name your price instead

Some US-based online retailers won't ship to Canada. At all. Period.

It occurs to me that there must be some amount of money that would make it worth their while to ship to Canada. It's certainly quite feasible to send something from the US to Canada, it's just more bother. Worst case you have to get some worker to stop what they're doing, package the thing individually and separately, take it down to the post office, and fill out some customs forms. There must be some dollar amount that could make up for that bother. Maybe it's prohibitive for most people, but they should at least tell us what it is. Just post on the website: "widgets $10, shipping to Canada $100". Either it won't be worth it to Canadian customers and the business can continue to go about life as usual, or it will be worth it and they'll open up a new market.

This could apply to many other areas of business as well. You ship by UPS? UPS is inconvenient to me. What would it take to ship my purchase by Canada Post or Purolator? Those are your hours? They're incompatible with my schedule. What would it take to get you to stay open an hour later? It would be much better business sense, and if they've researched their markets correctly it won't make any difference in actual operations.
