Why is a charge cord so expensive?

I finally cleaned out the junk from the garage, and now I can finally park my Volt inside. Although I had no problem with the 120V/12Amp charge outside, it would be nice to have a proper L2 charger in the garage, as the main panel is right beside the Volts charge port. I live in BC where there is no incentives for single home EV chargers, so I have been searching hard for a charger that isn't so expensive. $700CAN seems to be as cheap as I can find for a complete unit. I have found some for $450-500CAN after US conversion, but they don't have a cord. If I look for the price of a cord, they run from $150-200CAN. Why they heck are charge cords so expensive? The cord itself shouldn't be worth more than around $2/ft, that would be about $50 for a 25 foot cord. I looked for the price of a J1772 connector to connect to a EV, with no cord, and I only found 1 at alibaba for $96. Add the two together and that is the $150. But why the heck is the connector so expensive?
