If you are planning for a long trip abroad in some far away exotic island and your budget is somewhat in a bit of a squeeze and you are definitely looking for some corners to cut then maybe you'd consider getting some cheap suitcases. Acquiring second-hand suitcases is also an option for any would be traveler but going around looking for hand me down luggage is a bit disheartening, especially if you know that with just a click of a mouse button you'd be able to shop around for brand new but relatively cheap suitcases.
Going online will help you find the right suitcase for you, with so much choices available on the internet, it will be more helpful if you would decide on what specifications you'd wish to have on your suitcase, for example do you want a suitcase with several pockets inside or a suitcase with a toothbrush and toothbrush holder, do you want a suitcase with a water tight compartment for documents and money. Whatever you want, you'll probably find it online.
You will also be able to see lots of different designs with more options, color for one, you would be surprised at the multitude of available colors and patterns that you can choose from, you can also make up your mind on whether you want one with wheels or without but there are certain brands and models out there that have wheels that can be folded up or can be hidden into compartments with a flick of a switch, but I don't know if those are still going to be cheap suitcases.
One more thing to consider is the dimension of the suitcase that you are after, you'd have to foresee and in a sense know already what you are going to need on your trip and what are essential and what are actual space wasters. Choosing cheap suitcases can be really fun but a bit quite tedious, especially if you've yet to make your mind up on some of your preferences.
Lastly, you need to learn about what kind of material is best for your type of traveling and where you are planning to go to, some materials that make up your cheap suitcases might not be able to handle salt water and humid air, other materials might just chafe and crack in hot or cold weather, other materials making up your suitcase might expand or contract depending on the temperature and other materials might be susceptible to fungus or insect infestation given the right conditions. So, better research online and see if the cheap suitcases you've been eying will really be cheap in the long run.
