If I don't have time, what's the quickest way to get the most back from selling my stuff pre loved ?

I just sold a whole lot of furniture and other random stuff on various Facebook pages. I realize that people are highly likely to want to buy if you can provide delivery. I know lots of people who want to buy big bulky items but they have no way of transporting it. If you throw in delivery, you can up the price by a little bit to cover petrol costs. For example, today I sold a desk for 80SGD (UP 120SGD) and the lady instantly bought it without negotiations because of the free delivery.
