We're tightening things back up again (our family's choice). On our last Aldi trip they weren't sanitizing carts, didn't have sanitizing wipes for us to do it ourselves, didn't offer hand sanitizer, and didn't care about one way aisles or really any social distancing at all.
We'll do a once a month Costco shopping trip (later in the day is less busy) and maybe a mid-month perishables order for curbside pick up. By fall I hope to be restocked with 6-12 months of pantry goods and fully prepared for at least 6 months of not needing anything other than perishables via delivery or curbside every few weeks.
I much prefer once a month shopping now, anyway. I find I can buy ultra-pasteurized milk for the second half of the month, although I hope to have freezer space by fall to just freeze enough regular milk. Butter, cheese, and eggs store well. We pretty much only eat meat/fish we've purchased ahead and frozen. I bake our regular bread. We eat the really perishable produce the first week, potatoes within the first two weeks (too warm in house to keep longer, but I may be able to stretch it to the full month in the cooler months), cabbages and other sturdy produce in weeks 2-3, and have found carrots last all month if we peel and trim them and store them with a paper towel. The first week I chop and cook mirepoix (onion, carrots, celery) for soups, sautéed onions by themselves, and peppers and onions, and freeze it all for use later in the month. We fill in the last week of the month with frozen produce (fruit and veggies), along with canned/jarred fruits. All the flours, grains, and dry beans are stocked up every 6-12 months. I'm almost staying really well stocked on canned tomato products, pasta, canned beans, nuts, dried fruit, oils, vinegars, yeast, sugars, baking powder, etc. I maintain a sourdough starter, as well. I do think right now, if we were ordered to stay in our house and not leave for anything, I could feed my family for many months, although we'd run out of most produce.
For the first time ever, I'm stocking 6-12 months of OTC medications, vitamins and supplements, toiletries, and cleaning items. I never bothered to before, in part because our house isn't large. But with Covid, I'm even more motivated to declutter so I can make room for these items. It's been a lesson in creativity to store all of the extras (and the extra food).
Dog food is the only problem -- my big dog is fussy about food that's been stored too long, so there's no way to store 6 months worth of kibble. He eats Nature's Domain salmon from Costco. I may need to transition him to something I can order from Chewy, since Costco had shortages of dog food this past spring.
