Query: Packing Cubes are Surprisingly Helpful - and this set is the best price

Regardless of which type of luggage I'm taking (rolling duffle or structured rolling bags) these packing cubes are extremely helpful with organization inside. They allow me to compartmentalize similar items like underwear in one cube, socks in another etc. I've also been happy with them for electronic stuff - I use one for powercords and cables (for laptop, Zen player, camera, mobile phone) and other small attachments like my memory card reader for the digital camera etc.Very useful - and I've had some of these cubes for many years so they do hold up well. I like the Eagle Creek ones a little better but the Rick Steves set is by far the best price. And, Rick Steves is a travel guru by the way - if you don't own some of his books you're truly missing out. They are the best travel books on the market.
