Nice post @k0d3g3ar - 2nd hand items, especially 2nd clothing is really popular over here!
In the Phililpines, second hand clothing is called ukay-ukay and it's sold along the streets, in the downtown area, and in older run down shopping malls.
The locals love it because it's affordable!
P.S. You have an excellent business idea and I am happy that you are sharing it 😊👍
