The cheapest UK ask has dropped sharply—23.7% in the last crawl from £10.49 down to £8.00—so the market's softening fast. Half the listings here are played copies, which means a Near Mint example is actually the harder find. Asks span £8.00 to £12.00 with the median at £12.00, so that bottom-end listing is 33% under the middle; if you're selling at £10.80 you're pricing above the cheapest but right in the middle of the range.
