Whatever Iceman says it is
It's all individual preference. I like two data points (12mo / Last sale). Some sellers here ask more than GPA on books that have particularly good eye appeal or wrap, which is fine too.
Oh good from now on I shall use that
I try to pick a data point and stick with it based on the type of book, and the # of sales. Sometimes I might extend the data window if there arent a lot of sales. (like if there's only been 1 sale in 90 days, but 4 sales in 12 months, I'll move it to 12 months to get more data points). Usually I stick to 1 point (like 12 mo GPA) and then ADD the extra info that justifies my asking price (like a higher 90 day average, or a big bump in the last few sales).
Providing more info is fine, providing selective data is sketchy.
And all the X-men seller did was cite a sales range (800-1500 on gpa) but that sale price range doesnt line up with ANY data in GPA. No X-men 1.5 has EVER a recorded sale in GPA over $1029, so to note a 1500 sale is erroneous for sure.
Fixed the 1.0 to 1.5, but numbers you said are correct.
I am not trying to justify his pricing or his statement but when the first thing VETERANS do on the boards is say good luck your price is WAY to high, it is uncalled for. Say good luck and move on.
