I just passed the 36 to 38 quests. In the Halfling chapter, I needed to gain 404K supplies for #36, 505K for #37, and 606K for #38. I did each one in a single day. I did use POP spells on the third day, but I think if I had been more patient, I could have done it without the spells. For me, this was not really a big obstacle. The paying of large amounts goods has been too horrible for me as well. I just paid 17K of each Tier 2 good. That's 6 3-hour productions. So far, none of this has been traumatic, just time consuming.
