A lot of good insight in these posts (as usual
)
I agree with the human interaction input, but it seems like the shows are turning from a show for people to get cards and dealers to make money into a show for dealers and people to get together and swap stories and share collections. Personally, I like the latter more, but from a business standpoint, the former is obviously preferred.
Many dealers are willing to be reasonable, the others either go out of business or are located in an area with a lot of marks.
