You've heard it before: Most things at the airport are a total rip-off. Traveling necessities like food, refillable water bottles, books, socks and electronics should always be packed from home so you can avoid inflated airport prices.
你以前也听说过：机场的大部分商品简直是敲诈。旅行必需品例如食物、水杯，书，袜子和电子产品都应该从家里带，这样你可以避开虚高的机场价格。
The costs of goods typically surge at airports because of supply and demand. An airport eatery or shop is a traveler's only option for a last-minute purchase or meal, so if a traveler is in a bind, he or she will shell out the cash. In addition, airport rent space is very expensive for vendors, so retailers often hike the prices of their products to make a profit.
机场商品价格高昂和供求与需求有关。机场餐厅和商店是一个出远门的人在最后一刻想要吃饭和购物时唯一的选择，所以他如果有需求就会付钱。再者，对于供应商来说，机场的租金很是昂贵，所以需要提高他们的产品的价格来赚钱。
However, some items in duty-free shops (otherwise known as tax-free) are actually worth the buy. So if you're in a scramble for a few things before your flight, we compiled a list of the best steals.
不过，一些免税商店的物品实际上是值得一买的。因此，如果你在飞行前想要抢购几件商品，我们为你选了几个最划算的东西。

1.Alcohol
1.酒
In duty-free shops, alcohol is a great steal without tax, and can be anywhere from25-50% off compared to domestic prices. Plus, according to TSA, you can bring up to 3.4 oz on the plane, and mini bottles of alcohol are usually about 1.7 oz, so you can easily throw your purchase into your carry-on!
在免税商店，不含税的酒相当便宜，相比国内价格有25-50%的折扣。而且，根据美国海关标准，你可以携带3.4盎司上飞机，而迷你装的酒大约1.7盎司，所以你可以轻轻松松地将它们装进你随身的包里。

2.Tobacco products
2.烟草制品
Just like alcohol, you can also find great deals on tobacco products including cigars and cigarettes pre-tax.
跟酒一样，不加税的烟草制品包括雪茄和烟都有很大的折扣。

3.Hair and skincare products
3.护发和护肤品
Premium beauty products can be up to 50% at duty-free shops.
高级美容产品在免税商店的折扣高达50%。

4.Makeup
4.化妆品
Similar to hair and skin products, you can find top-notch makeup at airports with huge discounts.
跟护发、护肤品一样，你会发现一流的化妆品在机场都有巨大折扣。

5.Magazines
5.杂志
Although magazines are on the pricier side at airports, if you want some light reading for the plane, you can still grab a copy for a few bucks. It may cost a little more than you'd usually pay somewhere else, but the price difference isn't huge. And if it'll get you through the flight, this purchase is worth it.
虽然杂志在机场属于昂贵的那类，但如果你想在飞机上来点休闲的阅读，你也可以花点钱。价格可能比你平常在其他地方付的多一些，但差异也不是很大。而且如果这能为你消磨飞行时间，买的还是很值。
