You know those illiquid cards that take way too long sell, so you lower the price? I didn't double check what was on offer when I did so. The previous price I listed it at was 0.8/ BCX I decided to lower it to 0.69/BCX so that it would sell faster.
The second image shows someone having a bid for the card at 0.70 for 220 BCX which was matching the level 8 card in first screen. Given the feed is delayed, there's still a possibility that you could buy at that price and directly sell it to the bid. Even if that were not possible, I still missed out on 1 cent per BCX by not checking what bids were available. I sold a 37 BCX card thus the bid count decreased by that much.
