Beware! Thanks to all of you, who posted their reviews.
When I saw the mail, I got excited and decided that if they have the cash on delivery option then I will order from them. There was no cash on delivery option, hence decided to google this site. Only after that I realized its a fake site.
On looking closely i realized they had cited offer on galaxy s5 not samsung galaxy s5. Thank God, I was saved or they would have delivered a Chinese mobile to me.
