With all the social media hype, I purchased the buy 2 get one free special. When purfume arrived, I found it to be very low concentrate. Last for a hour maximum. Could be I got a bad batch but still, very very disappointed. Requested refund, so now I have to pay for courier to return spray, plus potential take a admin knock on my refund. Really had a bad first time experiencing with you guys. I will not be buying from you again
