Thats not the correct way to calculate 16% on anual basis since Junaid is not giving you
money to buy a console, he's actually buying console from a market and selling it to you and if its a question of riba/interest let me clear it will not be called interest in this case it will be called Murabaha in islamic mode of commodity financing in simple words cost based profit system, where seller is selling his own commodity with his desired price, its upto buyer if he's willing to buy it or not.
well there are manythings that can be suggested here but since this thread is poll based to offer installement services or not and I am 100% with it.. sometimes gamers like me who are even earning good amount on monthly basis can not afford to buy games and consoles even.
@Junaid: Idea is super meray bhai but 16% thoora sa ziyada hai I can suggest you to make 2 offers if you are willing to provide this kind of awesome service to us.
1 - keep the % a bit low for new consoles (your choice)
2 - put 16% on used consoles.
