Disowned, I Rose Via a Water Jar - Episode 6

A man sends valuable bike vouchers through a magic water jar to a woman named Erica, hoping this aid will improve her life so she can help him find collectible items in her time. He also asks her to urgently buy as many copies of a newly issued 8-cent monkey stamp as she can. Erica immediately visits a postal clerk named Kyle and purchases an entire sheet of the newly arrived, unpopular stamp. The transaction sets up their coordinated effort to exploit time-crossing knowledge for gain, with the man's next request already pending.
