Dr. Drib, they are all in my Amazon library and were all definitely free, it was before midnight my time (in California) but was just before 11pm for one post and the other was a little after 11:30pm. I try not to post so late, but sometimes it's either that or not at all and I figure some people may be able to get them before they go to regular price (after around midnight if they are 24 hour ones) and many times they may be free for 2 days or more. They have all been put in ereaderiq and if they have already been free once they may be again and either I or someone else can post them again.
