This show -- as any -- depends on what a buyer is hoping to find. There were definitely big time books and every bronze/copper/modern key in nearly any grade, many times over.
If you were looking for books to fill runs, or diving in $1 boxes for $20 books, it was possible, just not as many opportunities as years past.
My opinion is also skewed by attempting to buy comics from an era I know the least about. I saw good comics on Thursday with what appeared to be high prices (to me, again, not knowing very much), but after thinking about it, and going back for them another day, they were already gone. I snoozed and lost, but overall had a good time running around the conventional hall and chatting with many familiar faces.
