The Key Items You Should NEVER Buy at the Airport, From Duty-free to Bottled Water Or Risk Wasting Hundreds of Pounds

FAIR pricing is a rare thing in airports. A captive audience of consumers make for manifold markups, from expensive food to pricey parking. To save money, do some research ahead of time and compare costsespecially when youre in the market for one of these nine items.

Duty Free It may be possible to snag a good duty-free deal once in a while, depending on your airport. But its important to know that duty-free in no way ensures a good buy. USA Today reported: Duty-free is almost never a deal for the casual shopper out to get a bargain.

You can save significant amounts if youre a smoker, but youll find that electronic goods, beauty products and luxury items such as designer purses usually cost less online. The solution? When making duty-free purchases, do a little homework.

Go online ahead of time and do some cost comparisons beforehand. Foreign Currency Since currency exchange desks in airports often hit travellers with sky-high transaction fees, the airport is probably not the best place to exchange your money . It can be convenient, so if youre willing to pay the price for that, so be it.

A better strategy is to get foreign currency by taking out money at an ATM in your destination; this way, youll likely get the best interbank exchange rate, which is usually much better than rates offered at airport exchange counters. Contact your bank before your trip for more information on any possible foreign transaction fees. Bottled Water Its a no-brainer that passengers should bring a refillable bottle from home.

Stop buying water bottles in your terminal at 3 each and invest in a Vapur Reflex reusable plastic bottle, which is foldable, for packing into your hand luggage. Fill it up at a water fountain after youve gone through airport security. Itll pay for itself after just a few uses.

Souvenirs Plan ahead and be sure to buy your souvenirs before youre at the airport, waiting for your flight home. Airport souvenir stores usually hawk severely marked-up merchandise that can be found elsewhere for a lot less. There are exceptions to this rule, as some airports offer unique finds, like gifts crafted by local artisans.

Our advice, as always, is to do your research before you get to the terminal so that you can compare prices. You could even take a quick look at whats on offer when you land, and then buy whatever you need when you return to the airport upon departure. Neck Pillows Trapped in their terminals, travellers are at the mercy of anti-consumer pricing schemes, especially when it comes to particularly convenient travel products like neck pillows .

Order your neck pillow online ahead of time, and keep an eye out for special offers and sales. Try the MemorySoft luxury travel neck pillow, which comes with a travel bag, available on Amazon . Restaurant meals You may have noticed that restaurants commonly charge higher prices for menu items in airport locations than they do elsewhere.

Theres reason for this: Restaurants operating expenses are generally higher at airports than at street locations. But food costs can vary even by the terminal, heightening the confusion for travellers who want to compare prices. To sidestep this, bring your own lunch from home, as well as snacks bought much more cheaply from the supermarket.

Wi-Fi Although many airports offer free Wi-Fi, some hubs are still firmly entrenched in the dark ages, charging flyers to search the web while waiting to depart. Before you enter a card number, though, see if you can get connectivity for free. You can do this by sitting near the entrance of an elite flyers lounge or in an airport hotel lobby, both of which might offer free Wi-Fi thats not password protected.

Or try your terminals Starbucks. Although all Starbucks stores offer free Internet, airport locations are sometimes the exception. Some offer free connectivity; some dont.

Check the Starbucks store locator online before you get to the airport to find out. Magazines Youre not normally taking a big hit to your budget when you grab a magazine for your flight. But when overseas, watch out.

Imported magazines cost a lot more than those sold at home and can sell for well over the recommended list price at overseas airports, even if theyre old (mostly due to taxes and shipping costs). Stock up before leaving the UK to avoid these kind of charges or bring a good book. Parking Youll frequently find the better price at off-site parking lots, rather than at airport lots.
