I hadn't heard about this, so I did a little more reading at the New York Post.
I read that a "decoded bottle" is basically a bottle that has a sticker placed over the barcode on the box. How does this happen? Is is a "grey market" activity that happens when a company like Universal Perfumes imports bottles back into the country? I hope someone can help out here. I wasn't able to learn anything from a cursory google search.
