I received an email which says, among other things
"To celebrate 30 years of Native Instruments and our partnership with Akai, enjoy an extra 30% off your already discounted Komplete upgrade."
And then has a link for me to add the Komplete upgrade to my cart. However when I try to add the voucher from the email to the cart, I receive the message
"The voucher code 'xxxxxxxx' is not applicable for your current order. Please review the terms and conditions for this voucher."
I assume that this is because I automatically received a "special loyalty price" when putting the Komplete upgrade in the cart, even though the email seems to imply that I will receive both discounts.
It's fine if I only get one of the discounts, but how do I choose the voucher instead of the "special loyalty price?
