That is the nuts-and-bolts, yes, but there is more nuance to it.
I understand "a seller can put any price he/she wants on a book, etc etc" and that is not my point. I also understand he is not the only one to use the boards in this way but he specifically has caught my attention multiple times across multiple pre-boards venues.
The idea of the boards as a "community" is no longer relevant, but situations like this turn members here into pure dollar signs.

Thanks for the link.
This is true, but it has been less of a community than it was for many, many years.
To play devils advocate, even in the early days of there were members who only participated on the boards to sell stuff, even flipping books from previous board sales. It is what it is.
