Hogwarts Kryptonian

Dear customer, how can I help you?
Is it the Firebolt, the Vanishing Cabinet, the toys from Weasley’s Wizarding Shop, or the limited edition Philosopher’s Stone, Ravenclaw’s diadem?
Or even a three-piece Death suit?
I, Lu Yunkai, may be able to help you get it.
Of course, this requires money and a little bit of luck.
Believe me, as long as your financial resources are strong enough, luck doesn't matter.
Now, please tell me what you need and how many galleons you have, okay?
