dude do not try to buy genuine products at low prices they tag the real price on their website go and check it you think ok this price is good and also the place must be trusted.
and also when you buy an apple product check is it original and under warranty, seal pack (for this you need to know how apple company packing their product).
there is no turning or anything if you are being fooled...
I buy apple products at a shop in wadduwa. I know the price so I go there ask price and I the price ok for me I buy... all products I bought genuine, seal pack, original under warranty far for this.
