Where to buy Clive Christian in Dubai cheap? Fragrance

I’ve come across several websites offering Clive Christian fragrances, but I noticed a wide price range—from 800 AED up to 2400 AED. I have a few questions and would really appreciate your insights:

1. Do you know if websites like essenzi.com and parisgallery.ae are trustworthy? Also, is it safe to order from noon.com?
2. Where in Dubai can I buy Clive Christian fragrances at a lower price than retail, but still guaranteed to be original?
3. I’m happy to offer a generous tip for any helpful and reliable suggestions.

Thanks a lot in advance!
