In the UK, postcodes - unlike US ZIP codes, they're not free Retail product data - books, movies, music, games, electronics, etc: you can kinda do this through affiliate programs, but it's not great Drug companies - studies can be killed if the data looks bad; we should be able to see every study, completed or not, and all the associated data so we can do comparative analyses

I can't believe we have to pay for the postcode data in the UK. It should be freely available
