Were the MOQ for the resistors a major contributer to cost? Usually they're super cheap so even buying 100 is not a crazy problem. Also most PCB assemblers will have a generic component library for common resistor and capacitor values and footprints, which they encourage you to use anyhow because it's less hassle for them (they're often not even charged per part).

(And if you're assembling them yourself, then you can also buy kits of the common ranges to save the hassle and cost of having to maintain a stock)

If you have dozens of different passives on the board, then a dollar or two to meet each minimum order quantity adds up quick.
