The Saga of Ablution campaign is set in the post-magic apocalypse Fifth Era, a time of new technologies and discoveries. Therefore it has new stuff that can be purchased and used by your character. It is already assumed that you understand how to purchase goods.

You will not find any of the items from the main game's Equipment & Goods repeated here. You will be able to purchase items from that list as well. However, you may find it easier to just use the goods found here.
