I have been using amazon for shopping anything for a long time, the procedure of amazon is clear and transparent for buyers. first of all it gives all the intimation regarding our purchases instantly as SMS and shipping action takes place faster than any other sites I used. although it also send email for further need and clarification. in my recently purchase I canceled my order and it was good to know that amazon processed my request at instant, even after the item had been shipped, it got itself back all the way to them. Refund system is quite straight and easy, only matter of particular bank’s system. I am completely assured about the lowest price of products also on amazon and its offers. Only thing is remaining there that it does not yet accept wallet payment which is another best way of savings. One more thing about its ios app which I am using gets too much updates in comparatively less interval of time, besides it is an essential shopping app for any mobile. so for **great lowest safest** buying experience I recommend Amazon:)
