Olx is a great app. You can sell everything which is not useful for you, otherwise you will sell that item to a scrap dealer. I have sold a lot of items on olx. Earlier their app was good, but now there are so much annoying ads pop up in between. Otherwise a very useful app. Once I sold a samsung sub woofer on olx, which is a scrap for me. A guy from chennai want me to deliver it from delhi to chennai. It’s a very good app
