Post Office

The Post Office is filled with at least two–to–three–hundred owls, ranging from Great Grey Owls to tiny Scops (the latter for "local deliveries only"), hooting down from colour-coded shelves. The shelves are colour-coded based on how quickly they will arrive at their destination.

Withdrawing a letter from her bag and glancing around, Ana's sharp eyes scanned the speed of the owls around her.
Realising it would take all day, she turned to the man behind the desk, putting on her best innocent face.
"Excuse me sir, but which is the fastest owl you have?"
He smiled. "277. 15 galleons."
Ana made paid for the delivery and tied the letter to the owl's leg.
"He'll bring back your reply within two hours."
"Thank you."
Ana turned and left the shop, watching the owl become a speck in the sky and vanish from view. The assistant hadn't been lying, that bird was fast.

April didn't want to do this. But she had no choice. Her mother and father had to know about her sister coming to Hogwarts. April knew that they'd just tell her to be quiet, but she wanted to do it nevertheless. She walked over to the counter and asked the shopkeeper,"What's your fastest owl?"
The shopkeeper shook his head. "Sorry. We're closing." And escorted her out.

April was confused. The man didn't like her. Probably because he knew that she was no ordinary girl...

Casey entered to post office with a order form for her potion ingrediants.

Walking up to the shop keeper she asked. "How much for a delivery Owl?"

"It will be 20 sickles total Miss"

Casey reached into her pocket with her glove on, as sickles were made of silver.

"Here, I need it to take this order form and wait for it to be filled then deliver the filled order back to me"

The shop keeper nodded. "Very well miss, I may take a day or two."

"Thats fine, thank you"

With that done Casey headed back to hogwarts.
