Its real. I have a Chanel Exclusif, with a sprayer that doesnt look pushed down all the way, and the label on the bottle isnt perfect. I think what we have are commonly sold from the manufacturing plant to a distributor as 'SECONDS" or "DAMAGED" at a lower price.
Its like when your favorite clothing company has a sale and you get a shirt for 15 that usually costs double that, becuase it has a tiny hole in it somewhere, or the label is sewn on crooked... you get my drift.
You bought it for the juice right? Did you save a few $ buying it from that seller? Probably for good reason.
I have at last count 7 bottles that I consider to be "seconds" Juice is perfect, the bottle has some sort of defect. And I paid about 50% of normal retail for them, a few of them i paid about 20% of retail.
