First let me state that the following comment is not directed at Joey or anyone in particular for that matter, but a question to the Dealers on this thread in general.
I think it is interesting to see comments from Dealers on what is wrong with GPA, but in the same breath (sometimes in separate threads) explain that they don't report their sales.
Help me understand why you (i.e. the Dealers out there) wouldn't want to report your private sales to GPA? Logic seems to to state that participating properly would better reflect market dynamics and adjust future purchases accordingly.
To sum it up quite nicely: knowledge is power.
Frankly, it's not anyone's business what I or any other dealer sell their books for. If they're sold in a public forum/marketplace, then that info is free.
George got smart and said " I'll comprise all this public sales data, put it in a user-friendly database and market it." Voila! GPA is born!
For the record, I have no problems with GPA, nor do I feel it's "wrong." It may be off on certain books but it's a seller's responsibility to know that. If they do not, the market will take advantage of their mispricings. Pretty simple really...
Furthermore, why not? Is that not a sale between two parties? Does being a dealer give someone an exemption to not reporting?
Can't have your cake and eat it too....
