Fabricating limited supply. Retailers do it to the extreme on Black Friday.
But the people who really need your money can’t do the same. Typhoon survivors and cancer patients and the working poor. They have unlimited supply of need and can’t pretend they don’t.
“Instead” isn’t realistic because people love getting their Black Friday deals. But how about “In addition to?” In addition to spending money on stuff that’s in limited supply, take some of those savings incurred and buy some stuff where supply is truly unlimited.
Pick a cause and spend some cash. It’s a great deal. Even on Black Friday.
