I save money because I have Costco executive membership which also gives me Instacart for cheap, so I put those savings into the tip. Nets out about the same plus several hours of my life aren’t spent at Costco every month.

Many of us enjoy shopping, at least enough that what we would pay for it isn't much of a deal.

Just talking about why some people would want to use delivery even if they live close that’s all. Personally I can do without the chaos of Costco ha plus I go in person to my local grocers plenty in between.
