(Yes, I have a few extra copies myself, but they are not for sale).
However, I've just happened to notice that there are presently not one but two (2!) sets of said limited up for bid on ebay. These are the numbered editions (not the rarer lettered), and both have matching numbers.
The ebay item numbers are 221012911878 and 150806055324.
I don't know the sellers, and I can't vouch for them or the condition of their books. (I will vouch for the fact that these are gorgeous books, lavishly illustrated by Jeff Jones, John Howe, Charles Vess, and Tom Canty, respectively). These ebay sales have nothing to do with me, and I cannot tell you more than I just have. If you have questions, you will need to contact the sellers. But considering how often I get asked about those books, I thought I'd mention it, if any of you are interested.
Please be advised: these sets are not cheap. The books have appreciated quite a bit in value since publication.
