Generally a fan of packing cubes, though not necessarily Eagle Creek's prices. This drop actually saves about $15 off their typical retail price. That puts this set in the range of EC's more generic competition--from eBags, for instance. One thing to consider is that multi-pack pricing generally gives you a S-M & L assortment. I've found that sometimes it's better to buy separates so I can pack two mediums and a large, or two larges and two smalls, etc.. Either way, the idea is not to have to unpack them at your destination, but just to "live" out of them instead. Makes repacking for the homeward leg much quicker.
