This week, Kim Ah Young and Jang Dong Yoon join the cast for the "Spend More, Get Lucky. Jackpot Date." Inspired by the Sangsaeng Consumption Lottery, the cast pairs up for a special spending race where every purchase over a set amount earns them a lottery ticket. Along the way, games and missions allow them to earn extra Running Money, which determines their order of spending on a date. At the end, the three members with the highest totals will win prizes, while three unlucky random players face penalties. Who will strike it rich, and who will pay the price? (thetvdb.com)
