Remember that light energy can't be converted to electricity and also transmitted through the window; whatever percentage gets converted to electricity must be subtracted from the percentage that is transmitted. A window that converts 100% of solar energy to electricity would transmit 0% of the light; i.e. it would be opaque.

It just seems like the forces involved in accelerating and stopping would pretty much result in "puree". :-P

Let's do the math. To travel from San Francisco to Los Angeles in an hour requires an average speed of 166 m/s. Accelerating at 1 G (9.8 m/s), it would take 17 seconds to reach that speed. If that's too much acceleration for you, do half the acceleration for 34 seconds. Either way, no puree.

Do even huge online retailers like Amazon charge different prices depending on the country the items are going to?

Of course they do, and we've known about it for years. The Canadian government started an investigation into the issue last year. Even cars manufactured in Canada are cheaper to buy in the U.S. than in Canada.
