Please for the betterment of everyone, stop undercutting the price of a card that is already consistently selling at a higher price. I'll admit, I'm guilty as well, but if people would literllay just be paitient in most situations, it can prevent the cards prices from dropping and destroying any value that packs could have. For example, when a new LTD or champ comes out and everyone is selling the card that the new one could replace, people will panic, see what the current cheapest price is on the market, and then undercut that instead of simply being patient.
But like I said this is only if the card is actually selling consistently and it's not super late at night. If its late (past 1pm PST or 3am EST) theres not that many cards being bought or sold in general, so its hard to gauge. On a side note, prices for cards late at night are generally higher than any other times. Sometimes you can get the max value out of a card if you post it then, but that's only if it actually sells.
