I covered this topic just a bit in my
'Collectorisms' thread...
25. The War of the Discloses
The eternal, ongoing debate of whether or not the price of a card sold in the B/S/T section should be kept in the thread for posterity’s sake, or removed by the seller.
519. Fool’s Sold
Adding a new post to your own thread (that everyone is now forced to read) to declare that the card has been sold, instead of simply editing the title to reflect this fact.
915. Cost Suppressant (refer to
#25)
The deliberate removal of the asking price of a card in a thread after it has been sold.
See also: Sticker Stifler - a seller who chooses to edit out the price of his card to make it now read something to the effect of “$SOLD.”
See also: Dollarsense - the argument that leaving the sales price in for everyone to see is beneficial to the entire collecting community.
See also: Stetsman - someone who abides by the principal of leaving his asking price in and unchanged following a sale.
