Potter's magic primed, packaged and ready for delivery

DENVER – Harry Potter relies on owls to deliver his mail. Everyone else waiting to read the final installment in the book series has to rely on the U.S. Postal Service and delivery companies.

The Postal Service will deliver the books to five retailers and Internet shippers including Amazon.com, Barnes & Noble, Walmart.com, Anderson Merchandising and Baker & Taylor.

According to the Postal Service, approximately two million Harry Potter books will be delivered on Saturday. More than 55,000 copies are allotted for Colorado, Wyoming and Montana.

"We expect to successfully deliver every Harry Potter book our Denver Post Office receives for delivery on July 21," said Denver Postmaster Alan Catlin. "We know many children and Harry Potter fans are counting on the magic of the Postal Service to deliver like Harry always does."
