Buy adhesive shipment only when needed
A direct but costly way to fill an adhesive shortage for a specific crafting job.
General vendors that list an adhesive shipment in their stock.

Stop buying once the planned mod is covered or the price would delay a more important purchase; switch back to crop production and scavenging for ongoing supply.
