I can almost guarantee they're fake.  Lacoste is to nice for someone to have a friend selling them for $30 online.  Lacoste will only sell to select stores, you CAN'T just wholesale them.  And whoever says that it doesn't matter if they're fake, you stupid, just because they look the same doesn't mean they are.  Real Lacoste shirts come with Mother of Pearl buttons, which are pretty rare, and bump the price up from any other polo.
