Where can I get Louis Vuitton fragrances for cheap?

So I went to a perfume sample store with some friends yesterday, and there were many brands like Louis Vuitton, Guerlain, Maison Francis Kurkdijan, Parfums de Marley and many more. The brands I listed have impressed me the most, especially LV with its Pacific Chill and Afternoon Swim. Pacific Chill smells very unusual and fresh but a bit too sourly agressive and Afternoon Swim is more balanced but a bit too weak. Id really love to own one of them for upcoming summer, but they are very expensive for their performance. I know they are expensive soly because of its brand, but is there any place you can buy them for cheaper and i dont mean cheap fakes like turkishsouq and pages like that sell.
