The place to get packing cubes is eBags. I recommend their own eBags brand, much less expensive and just as good as the Eagle brand.
Their prices are also better the Eagle folders, eBags does not have their own brand for those.

thank you for the info!!

since you use them, do you recommend one size cube over the other? It sort of seems the large size is a bit of a waste, since you can almost fit too much in there, knim? What about the folders - there's a couple sizes, correct? I assume at times you use all 3 sizes of cubes for different needs, but just wondering if you 'never' use that largest size.

I am also VERY glad you are staying on for the 3 day and I think you will appreciate that solo cabin after the wildness of three generations crammed together.
, so I drag dh and the kids in, and show them the pieces I've seen on-line, and all the cool pockets, and things that snap in and out, and pockets, and more pockets... and I just get so excited!
Not one of them got excited with me though
, and my dh was even visibly annoyed after a little while. Needless to say, no new luggage. I'll have to go get some cubes and folders though, and that should be a good 'fix' for me! And I'm definitely going by myself!
to them all! 
Can't wait!!! Hoping all of you have a great weekend!
O the joy of growing up!
