You have to return the item first. Fnac will refund or exchange several days (sometimes weeks) after receiving the damaged item. Black Widow will likely be sold out before November 12th, so you won't be able to get a replacement as it looks like they don't keep any backup copies.
From experience, they tend to "forget" to send the replacement item and you have to contact customer service (which is pathetic). For safety, I always order 2 copies (when it comes to a special Fnac edition).
