There are a few things going on in the MODO secondary market that are interesting or frustrating or both:
* Prices often remain wrong for some time after new information becomes available.
* The terrible usability of MODO Marketplace makes buying and selling of cards unwieldy.
* Almost everyone is doing almost everything by hand.
* The behavior of all parties is probably not strictly-classical-economics-rational.
There might be some value in (a) trying to make money in the market in an automated way; or (b) offering some kind of "better" service for those that buy and (particularly) sell cards; or (c) both.
What I don't know is how the people that sell cards actually sell them. I know Ben, Gary and others have sold lots of cards.
Questions for those that have sold cards:
How do you do it? Through the Marketplace?
What kind of prices do you get compared to sell prices?
Is it easy or painful or somewhere in between?
