Well, I have purchased a L3+ on their official website  3 days ago. I have done a wire transfer very quicly (2 hours after the purchase) because Bitmain clearly said that "if money wasn't transfered in 72h, the order will be cancelled".

The problem is now this one : I have ordered the Antminer L3+ 75 hours ago... and haven't received any additionnal mail from Bitmain. Moreover, I don't know why, but I can't access the same account page than yesterday... where I was able to see the order status. I'm kinda affraid!
