Watch your blood pressure before you get an aneurysm.
It is very simple, the 6 mounts would under normal circumstances be 150 euro, but right now with the discount they are 49.99, whether or not mounts on the store er overpriced or not in general is irrelevant, it is still much cheaper and thus a very generous discounted price. Would I buy it? No because I don't want to spend 44.99 on cosmetics, but it is still a good discount, no matter how much my comment seemingly offends you.
