A seller, better be politically correct and say, a “serious collector” LOL, or a dealer, liquidating at half of market price, is removing prices as a courtesy to others . Others who ? I can only think others, as other “serious colectors and dealers”, as I see prices removed as well, when they sell at twice the market price .
Your logic is always biased to business, and in this case, ironically, you proved wrong and rigth at the same time, go figure !
In reality, what they are doing, is protecting their business, and their friends’ bread and butter, as well .
