Supermarkets should be able to write off the expenses (transportation, stagging, etc) related to donating soon-to-expire foods to food banks. And not just normal income deductions, but actual direct deductions from taxes. That is, if you spend $1000 loading and shipping expired food to the food bank, you pay $1,000 less in taxes.

Truly incentivize giving food to the poor.

Yeah, there's solutions to this problem and the idea that all of them don't do this a failing of the store's management.

France had to pass a law that banned food getting thrown out that could be given away.

I also noticed that Costco started offering more prepared chicken foods after it became more well known that their cheap rotisserie chickens would fill dumpsters at the end of the day.

My tiny local market does 40% off and then FREE for products near expiration.

Fred Meyer (owned by Kroger) sells close dated food at half price. Produce with blemishes is set aside and sold in reduced price bundles. I am sure they still throw away plenty of food, but the reduced prices do seem to attract buyers (myself included). Some items just never make financial sense at the regular price, but half price? I'll take it.

Hypermarket? How does that compare to a supermarket?
