When it’s time to go grocery shopping write the current date at the top of your grocery list.
Having the date in a easy to see place makes for a quick way to check how much time is left for use by dates on dairy items and fresh produce. My watch does not show the date and my mobile phone is in my bag and honestly I can forget the date in my head from aisle to aisle.
I can’t go shopping without my list as I tend to buy a whole heap of stuff not listed so nothing I need for the next week and I tend to run out before the next shop.
I don’t mind fruit and vegetable shopping more than once a week but I refuse to do grocery store shopping more than once a week.
