I can say with a lot of confidence that the perfumes are diluted. aka FAKE.
You got to own lots of genuine ones to tell the difference.
The only place to get genuine perfumes for a lower price is from Dubai, and that too if you know where to go, else 99% of the time they are diluted.
Even I used to receive SMSs from FnU. Sent a strong worded email to cc, they stopped immediately.
