So far we have received 2 out 3 boxes. The first book was for Ender, which is a well loved book, but we already have a couple copies. The second book is for Artemis, which we also already have. It wouldn't be so bad if you felt this was sent from the seller, instead you get an Amazon box and you can return the book to Amazon for credit. Book one and two I have returned for right around $10 for each book. So if the seller has an Amazon account with free shipping that would mean I am paying 23.90 per month which is almost 14 more than I am receiving in value. I would not recommend. You could also randomly pick a sci fi book on Amazon and ship it to yourself for less.
