Maaverix, I can't comment because I do not know the fine print nor have made use of this service.
I know that in Brazil it does exist. Shops (incuding airlines) will split the payment over a few months interest free. So, if you buy an airline ticket for QR1500 and elect to pay over three months interest free (the airline/shop needs to give you that option, though), then you are charged QR500 per month over three months. No interest. But that's in Brazil, here I do not know how it works.
