Whenever a buyer wants me to deliver, I usually tell them that I don’t deliver but will take $5 off if they pickup. Saying this usually separates the serious buyers with cash in hand from the tricky buyers that just want a lowball or handout. I’d rather price my items higher to be able to reduce it by $5 so they can pickup and I can save my time and gas. The tip-off is that OfferUp has shipping and tricky buyers avoid it so they won’t have to pay for delivery. So I don’t deliver and use the shipping option instead of wasting my time driving just for a delivery. Let me know if this helps!
