I was looking at an old classic called "Riddle Of The Sands" by Erskine Childers (an excellent pre-WW2 spy novel).
Kindle Store lists no less than 9 editions ranging in price from 99c to $8.75.
Since none are abridged, one may assume that they all have the full text.
What I cannot easily work out, therefore, is what I would get in the $8.75 version that I would not get in the 99c version. There seems to be no obvious place to find that out on Amazon and so I wondered if anyone here might know if I am missing some obvious way of comparing them?
