I shop 1a month sometimes every 2 months. I live wayyyyyyyy out in the woods. I grow my own veggies , fish a little bit. Pretty self sufficient out here as long as I don't get sucked up by a tornado LOLI think you can do click and collect now.
You also probably need to go to the grocery store more often, like once or twice a week. That means more exercise. How do you ever have fresh food if you only buy once a month? Thats not really healthy to have month old food. Bread goes stale within a day!
