I can't imagine spending thousands of dollars on content without getting a detailed summary of what the purchase would include. I've bought bulk packages before & yes, there are usually at least a few sets in niches I don't push. But before I buy I make sure there are also enough sets of girls I can use, making the purchase worthwhile. This should be common sense!
14 sets out of 700+ is an acceptable margin. At less than $10 a set, 14 out of 100 is an acceptable margin.
(BTW, I'm not defending Aaron in any way, shape or form. I think he's being a complete prick, but it's also within his rights to do so. For future reference, an ICQ log is not a binding contract.)
