Smart travel: items to avoid buying at the airport

We can all agree: flying is already expensive enough without falling for those pre-flight temptations. And while you can find practically anything and everything past security, your time waiting at the airport can quickly add on extra costs. This is especially true if you spend on certain things without thinking it through. From drinks to neck pillows, some things are simply not worth buying, be it for your wallet and even your health.
So before you fly, check out this gallery for the things you should always avoid spending money on at the airport.
Wi-Fi

Just like most people, you probably feel dependent on all that online connectivity. However, just say no to paying for Wi-Fi in the airport.
Electronics

Tempted to buy a new charger or headphones? Think again! Electronics purchased at the airport will cost you significantly more than if you had bought them ahead of time.
Souvenirs

Whatever you do, don't buy souvenirs at the airport. They're known to have an astronomical markup.
Water or other drinks

Air travel can dehydrate you, among other physical side effects, but seasoned travelers know not to buy water at the airport.
Food

It’s always a good idea to eat a good meal before you fly. Whatever you do, don’t buy your food in the airport.
Foreign currency

It's probably one of the last things you'll think about when planning a trip, but don't exchange your money for foreign currency at the airport.
Booze

Many people stop at Duty Free because of the common misconception that they will save a fortune on taxes.
Neck pillows

If you're going on a long flight, make sure you purchase your neck pillow before your trip.
Rental cars

If you want to get the nicest car, at the best price, and with the least hassle, arrange this before you arrive at your destination.
Reading materials

While your brain needs books and magazines, don’t wait until you get to the airport to think of this!
Parking

Airport parking garages tend to overcharge for long- and short-time parking.
Luggage

Anticipating doing a lot of shopping at your destination and thinking of buying an extra suitcase at the airport? Don't!
Chocolates

We know: chocolate is oh-so-good! But don't buy it at the airport, and certainly not in the Duty Free shop.
