France’s ban on grocery stores throwing out edible food,
stores in America do this to (not all but some). I know for a fact the store i worked at before gave away most of their produce that they can't sell (bad or just will be bad) to the local food pantry / homeless shelter.
Just shop more often
There's also the factor of gas money and time to do this where some people don't have time to go multiple times a week and the money to go back and forth.
But there’s a catch. Ligon’s research also revealed that people regularly buy groceries from three to seven different stores.
Could we see the data they got this from?
