Hey direct away, what I'm saying is that from an incremental point of view the total cost of slabbing a number of BA and Modern books verses their valuation Raw starts to not make sense at a certain number. So yes the cost of $2 should not be your prime determinate and if it is then yes you are probably doing it wrong. However slabbing of $27 and $38 per book, plus shipping both way starts to eliminate the utility of a lot of BA books not in 9.6+ that's all, or at least increases the potential for one to reconsider.
