I dunno if anyone is looking for these, and don't know how long they're going to be on sale, but the trades are all available on Kindle for $6 (normally $35). This includes the two Road to NML volumes. The Kindle books do add to your Comixology account.

I just bought all four of the main volumes for myself - I don't know if I've actually read the new collection. I know I've done at least most of the old collection, but it was well over a decade and a half ago.
