I've been buying books off ebay to finish up my collection. I bought some Give Yourself Goosebumps books and of the seven I bought, three of them (from three different sellers in different locations around the USA) had their covers cut off. I've taped them back on. But like... what is this? These covers are very clearly cut, with a scissors or knife, not ripped or bent. What on earth would be the reason for this? I'm so confused.
