We pre-registered a dictionary .london domain we had a trademark on for £200 as a potential switch from the longer .co.uk we were using. When it came to sunrise, our registrar told us that .london told them there was an error and our domain hadn't actually been pre-registered but was now available for £5000. I consider it fortunate that we got the early warning before investing money in rebranding.
