Pack of 12 cartridges at a bargain price. A flat due to this purchase: delivery by the carrier (Chronopost): frankly disappointed, the driver did not find my street ... (I thought that these providers had updated GPS ...) And would have called me (nothing on my laptop ...). In short, 50km round trip to pick up my package in an industrial area (fortunately, I had my GPS can be a conversion in Chronopost to consider !!!!!)
