One last Tajdeed

From the Royal Mail website..

Introduction

The only time you'll ever have to pay to receive mail is if your mail has come from overseas and there’s a Customs charge to pay or if the person sending it hasn't paid any, or enough postage. But don't worry, you'll still get your mail. We'll hold it at the delivery office and send you a 'We're holding an item of mail' card, letting you know how much you need to pay. You can then put a stamp for that amount on the card and send it back to the delivery office, and we'll deliver your mail. Or if you prefer, you can collect your mail from the delivery office and pay the extra there.

And with that said...
