You don't need the LN-CC code anymore to get the discount. Everything is discounted now, as far as I can tell. Maybe you can't get free shipping anymore though.
But if you saw something you wanted, you can still get the discounted price. So you are in luck.
Were people looking for 30% + VAT off of what is already marked down by 30%? I don't think that ever worked, unless you were a special flower. I used the code a few days ago. The code would not work on the MMM stuff that was listed as 30% off, except to give free shipping. The code worked on full price Lanvin items.
