I've noticed more and more book sets are now listed on Amazon under the heading of Health Household and Baby Care and many listings are described not as used books but "open box". There are many book sellers listing this way. These sets used to be under ordinary books asin's, but not anymore. Is there any way around this gate for AOB users? Some examples of this are Clive Cussler complete set and John Jakes Civil War trilolgy.
