I'm pretty sure you got the number wrong. As Jouho said, you'll want to check it again.
Aventus doesn't come shrink wrapped, so no worries there. Also, the cap on mine is really loose too. In fact, I stopped using the cap to prevent myself from ever accidentally picking the bottle up that way. It's loose. Is the sticker label starting to peel on your bottle? Mine is. Isn't Creed quality control awesome? Luckily, the scent only costs a few dollars. Oh, wait...
Really, it all comes down to how it smells, and Aventus smells wonderful. Enjoy it.
