If you move your own vases, since any loss is borne by you, you are motivated to take all necessary precautions. Someone who you pay is not so motivated, increasing the chance of loss, but the insurance then mitigates the risk. If you just pay $20 to someone on Craigslist, neither of those is the case.
Two of the main resources people have are time and money. The world offers many opportunities to trade one for the other, at widely varying rates.
I've often heard people recommend trading money for time in the abstract, but this advice is rarely accompanied by specific recommendations on how to do so.
How do you use money to buy time or otherwise make your life better/easier?
