Sounds like they under priced them. Seriously. If it only took 10 mins to sell out.
That's a strong possibility. As an economist, that's my take as well. . . but on the other hand, we cannot make that judgement too quickly. What we have here is the eagerness of the first adopters. Can the product sustain such higher than world market prices of $10k - $17k? The $20k price being paid are those prices plus Chinese government value added levies for products sold in China. Imagine the arbitrage that will be going on when $10K plus sales tax can get you $20K in China merely for sneaking one across China's border.
