Hermione did not drop it in the bin. She’d slipped it into her robes under the table and dropped the empty box in with the rubbish. She hadn’t decided that she would use it, but she wasn’t quite ready to give up the option yet. She rolled it around in her pocket throughout the day wondering why it had been delivered to her. Maybe they had mixed up an order and sent it to her by mistake. By the end of the day she’d decided to keep it, she’d thrown the box away after all, she couldn’t likely return it now. With her next order she would include a note explaining that it had been sent to her by mistake and she’d unknowingly opened it, so to please send a debit to her Gringott’s account for the cost.
