Semiskimmed is right, though. They generally sell very quickly. I've made upwards of £30 since they arrived on the platform. Goes nicely towards games.
The trick to getting rid of them immediately is to choose to sell the card, then check the end of the graph to see what the last one sold for. Undercut that by 2p or 3p, and it should sell within minutes.
So, you see on the graph the most recent is 13p. Type 0.11 into your price box, it should then have "Customer pays 0.13", and put it up. If you want it sold even more quickly, enter 0.10 instead (dropping 3p below the last sale). The vast majority of cards that you market like this will sell within minutes.
If they annoy you so much that you can't be bothered doing that, I'll take them off your hands.
