My fridge might look better if it weren't that our humidity is such that I keep two large bins of seeds (I'm the
local bank for at least 2 other families as well as us) and two bins of herbs/spices. I'd go longer without shopping and use the freezer, but I've got others with addictions like commercial yogurt, that they like to indulge.
I think it's great that you guys are managing 4-6 weeks - well done!
