Traveling is expensive, that's no secret. From booking flights to hotels, cheap is never really a word we would use to describe traveling. When you can lighten the financial load, that's always a plus. I often find it helpful if I pack items that you might typically buy when you're traveling.
Most of these items will often cost you more if you buy them at the airport or once you've reached your destination. If you take a moment to check these items off your list before leaving then you will be saving yourself both time and money. (Two things we all need a little bit more of, no?)
Whether it's a book or a magazine make sure you've got it ready to go before your trip. If you're a Kindle person like me and consequently have Amazon Prime, you will find that they offer plenty of free books and discounted magazines. I always make sure I stock up my Kindle with plenty of light-reads for each trip. Magazines are another staple of mine but can be very costly at airports. Your best bet is to check your local bookstore or see if any of your friends have old issues they will lend you.
I had to capitalize this one, not only because I'm a foodie but because airport food costs a fortune! I like to hit up a local store and buy a box of protein bars, usually at a pretty discounted price. They pack easily and will fill you up for those in between waiting times. Trail mix is also another great snack to pack, it's even cheaper if you buy the nuts and dried fruit yourself and create small baggy's for them. You could easily spend $10 and more on airport snacks that aren't even that great.
Now we all know you can't bring liquids through airport security BUT if you wise up and purchase a water bottle with built-in purifier you can fill your bottle up at the water fountain after you've gone through security. A bottle of water cost at least $3 at the airport -- who feels like that?
Not traveling to some place tropical? Skip this one. However if you are on the verge of a tropical vacation bring your own sunblock. Vendors in tropical climates realize that many tourists will either not pack sunblock, or run out. That being said, its no surprise that they will jack up the prices on sunblock, because they know they can make money on it. (One of the best tricks I've used is to take a regular 6oz bottle of sunblock and squeeze it into two 3oz travel sized bottles. This is very clever if you don't want to check your luggage...you'll be able to save quite a bit of money this way.)
These items you think would be a no-brainer but how many times have you seen people purchasing ear-buds and chargers from those Best Buy machines? Generic chargers and headphones can cost around $5-25 depending on where in the world you are, airport prices will charge at least double. And sure, you can buy some off the street if you happen to be backpacking through some Southeast Asian country, but those crappy fake products will only last a few days before they break. Trust me, repeatedly experience. (And always remember: you get what you pay for...unless you are buying it at the airport)
If you take the time to purchase a few of these before your travels you will be pleasantly surprised how less stressed you will be not only mentally but financially as well. Having a snack handy and a good book can go a long way. Happy travels!
