* Note: Now there is no in-app payment (it is agreed between the seller and the buyer to pay a commission for the application)
For the payment , we do not need it for now . What we need now is the Customer has to accept our terms and conditions which is take percentag if the Customer sells through our app . And this is what the apps in KSA do . It is familiar
