Buy multiple hero cards still available? (PC)

I believe we used to be able to multiple hero cards for a discounted price. Is this still available or has this been removed? I can't find it anywhere in my store (PC) I really don't want to pay 2000 defender medals or 450 gems for a card. That's quite a bit of resources. I hope to get a discount on multiple cards... 

Hi,

Yeah we were having problems with it out of nowhere. So we had to remove it from the emporium. As soon as we fix it it'll go back up in a future update.

To clarify, the discount only applied to using gems.   It never applied to purchasing a 5 pack of cards with defender medals.  It was always full price, 10,000 medals.   The only benefit was convenience.
