TAIPEI (Taiwan News) — One lucky shopper won NT$10 million (US$336,570) in the November-December receipt lottery after spending only NT$13 at a 7-Eleven.

The shopper paid NT$13 for a service handling fee at a Xindian 7-Eleven store in New Taipei. The winner was one of three 7-Eleven customers who won the NT$10 million prize, according to SETN.
