How much can I get if I sell soju bottles and empty bottles?

pu1. If you bring me an empty bottle of soju, I give you 40 won per bottle. Some places give 20 won depending on the neighborhood

OK

pu2. Until 2015, the deposit for soju bottle and engineering bottle was 40 won, but it has been increased since January 2016, and now it is 100 won

OK

pu3. It's better to bring it to E-Mart, Homeplus, or Lotte Mart. Local supermarkets often don't give you a good price. I do it even if I'm lazy
