All of the sudden yesterday I noticed our sales increased by almost double in the UK - and I use Appshopper to consistently check the stats. iphoneappsplus.com seems like it only updates once a day maybe. I wish Appshopper had a UK site so I could see what's going on - besides checking iTunes UK...
Plus 1 on that. It's the second biggest market. I think arn appreciates the size of UK visitors to his websites though, I notice a lot of UK-related posts on macrumors, so maybe he's already thinking about it. Anyway, maybe this is the cause for your jump: http://www.pocketgamer.co.uk/r/iPhone/Ravensword:+The+Fallen+King/news.asp?c=17216
