Browsed the Amazon book offers for four hours. I want delivery to my parents' home because I will spent the first week of vacation there. Thus I need immediate availibility. I found two book, looked a bit further and when I came back one of them had changed its delivery time. Gah! I went looking for suitable replacement and looking and looking... I went to bed 2:30am. Fortunately I have not much to do today barring unpleasant surprises.
