Whitmor Wire Storage Cubes

That is the brand that we noticed the larger spaces first.
The ISBN between the large spaces and the small spaces are the same so there is no way to tell.
Is it free if you decide you don't want them when you go get them?
You wont know until you look at the box picture because the spaces aren't listed on the box either.
Edit:
I also get annoyed with the Whitmor connectors the most, they are so difficult. I've been getting my cubes at bed bath and beyond because I get the coupons and it calculates out to be just cheaper per grid than the others.
