[2020] Ability to buy supplies

Hello @Gramps, Thank you for the question.
The reason we do not have this in the game is because to produce supplies does not cost any other resource/s. So it is deemed more economical for players to build workshops to produce them.
Power of Provision spells are also available in the game (Neighbourhood Help, Tournament and Magic Academy) to boost production in Workshops to also help.
Hope this helps.  

And don't forget this little guy here:



You can use it on any cultural building, usually on buildings that get polished. It will add 5% for each one. Elvarians like powerful suns.
