UK Fans: Chance to win set of Heroes and Villains stamps featuring Dumbledore and Voldemort

To coincide with the recent DVD and Blu-ray launch of Harry Potter and the Deathly Hallows - Part 2, the Royal Mail is launching a very special presentation pack of Heroes and Villains, featuring Professor Dumbledore and Lord Voldemort.

A flyer for the stamps is included in every Blu-Ray and DVD copy in the UK. As you'll recall we posted about these themed stamps back in March.

The stamps are currently available right here, but MuggleNet is also offering five (5) UK-based fans the opportunity to win a pack.

Just answer the following question: Name the UK release dates for all eight Potter films (in theater, NOT DVD or Blu-ray releases). Send your answer with the subject line "Royal Mail" to mugglenetevents@gmail.com.

Winners will be selected AT RANDOM and notified via e-mail. Good luck!
