Let's just say that he takes full advantage of a free market and there's nothing wrong with the gray market.

托马斯：这么说吧，他充分利用了自由市场，灰色市场并没有什么问题。

Thomas says, " there's nothing wrong with the gray market." The " gray market" is in between the free market and the black market, where buying and selling things is legal but it somehow seems wrong.

托马斯说：“灰色市场没有任何问题。 ” “灰色市场” 介于自由市场和黑市之间，买卖东西是合法的， 但不知何故似乎是错误的。
