I Don't Know If Korea Does Couponing To The Extreme Like The US Does, But Let's Say It Does In Solo Leveling's

I don't know if Korea does couponing to the extreme like the US does, but let's say it does in Solo Leveling's version of Earth.

Sung Jinwoo would 100% be that guy who treats it like an extreme sport with 10 books of coupons stashed on his desk and when he goes to check out his $250 worth of groceries, he whips out his coupon BINDER and the cashier starts crying.

And then Jinwoo's receipt shows that he paid $2.14 for all of that.

That's the story of how Jinwoo and Jinah scraped by when he was still an E ranked hunter.
