Cash4... Posting Letters!
From the site:
Research International is the independent company responsible for monitoring the service provided by Royal Mail. Royal Mail makes use of the results from our survey to identify problems and fix them as quickly as possible. We monitor the mail service by having a large panel of volunteers all over the country sending test letters to each other and providing us with the dates of when they posted and received the test letters (of course we fully pay all postage costs).
Joining the site is free and there are rewards, including free postage, vouchers and ca$h!
