Concept - Main concept of Olx application is to
Buy and sell things near buy you
Its like if you have some stuff which is not usefull to you you can sell it on olx and you can also buy some other stuff from olx
For Example - I am having Redmi Note 3 but I bought a new phone now I just have to click a pic of my phone, add some info about my phone and set some price and upload it to olx now this ad will be visible to others so it is very helpfull
And I can also buy things from this app
I had sold my old tv from this app
This app is very usefull for buying and selling things near buy you
