Does Voucher Cost of Food Increase?

I know the gem costs do.  And I know the total voucher cost scales based on how much food it takes to fill your silo, but can I use vouchers to buy food without worrying that it will eventually become way too expensive?

I don’t think so. The food cost seems to be the same as it has always been.

No the cost never up. Yesterday I was at level 88 and I spend some voucher to up at level 89 and refill my foods to do like over 100 raids and more. its 88 voucher when you are empty. good if you want to win league or level up

don’t afraid to use it. Depend of the foods you still have but if you wait to be empty its 88 to be full
