hello.

I have 2 unused promotions codes and i would love to apply 1 of them on legendary items.
just change the calculation. for example a promotion code cant decrease the store prices for more than 15-20 coins!

that would be nice.

No, they stated many times the codes will not reduce the price on legendaries.
