Packing cubes are on steep discount today on Amazon.com

This is one of those things you didn't know you needed until you use it once and it changes your life. Traveling with packing cubes is an organizer's dream and will make sure that your clothes and other essentials don't get mixed during the packing and unpacking process. And best of all, packing cubes actually help you maximize space in your luggage (unless you have a spherical suitcase...then nobody can help you).

Seriously, they are the best. And at this low, low price on Amazon, you can't go wrong.

If you don't know where to start, here are some recommendations:

• The original packing cube set (2 sets of these will be great. They fit inside each other nicely).
• A shoe sac. Very handy.
• Hanging toiletry kit.
• The Pac-It-Sac set. I use these for EVERYTHING.
• Clean + Dirty packing cube.
