Can't buy voucher with 50% discount after eEDA + Premium

Hi, i tried to reach support@ine.com but since i didn’t received any feedback yesterday, there is it:

I bought the eEDA + Premium months ago, and since it should drop to 200, the price is still the same. How to proceed? I still have the premium subscription active.

You use the voucher code you receive by email on checkout. Kind of like a coupon.
