我留意到，在美国的开架超市和商店里，珠宝等贵重物品都是锁进玻璃柜的，香烟虽不贵重，但也上了锁。

I noticed that in the United States, open-shelf supermarket and shops, jewelry and other valuables are locked into the glass, and cigarettes is not valuable, but also on the lock.

就连一些并不贵重的物品，如一部大约1720年包含5张地图的地图集，期望售价约为150美元，最终却得到了2 960美元的拍卖价。

But even modest pieces, like a collection of five maps, circa 1720, that had been expected to go for perhaps $150, ending up fetching $2, 960.
