As you may know all our mail is now scanned by Royal Mail so they know what is in the envelope. Unfortunately some unscrupulous postal workers in Edinburgh have been using this scanning process to open birthday cards which contain the odd £5/£10/£20 note. This has been confirmed by Royal Mail. Don't ever send money through the mail service, and don't send vouchers this way either. Christmas is fast approaching and many of us send Argos or Boots vouchers to family and friends. Vouchers are just as valuable to them as cash. If you get a proof of posting and you wait 15 days after you expected your letter to arrive, you can put in a claim if it has gone missing but the difficult part is proving how much you put in. Please, don't send money or vouchers through the post.
