I have none. We pretty much have only 1 grocery in store that bends us over. To go to a real chain store we have to drive 20 mins to the next town. I needed mayo and they only had the small squeeze bottle. They charged me $5.99 for it!!
You can make your own mayo (I’ve done it) with basically oil and eggs and a blender. I buy my mayo now at Costco, 1/2 gallon bottles when they on sale. I transfer to two quart jars and put in the fridge.
I’ve been getting most of my groceries at Costco. Rarely buy processed food. I get mostly organic produce there, things like rice, beans, flour, oil… all kinds of stuff, but almost all is edible. I have gotten many non-food items there but most times I go it’s only for groceries (I go every 2 weeks for the most part). I buy gas there too, but am driving around 500 miles/year, so that’s rare.
Costco has many basic things at competitive prices, including spices and herbs, what seems to me a great variety of cheeses, dairy, I’m not all that hard to please, mostly I don’t have fancy tastes. I don’t buy their prepared stuff ever. I pick up on the free samples, that’s fun. I wear a mask in the place!
If Costco doesn’t have the grocery item I want, I’ll pick it up at Trader Joes (a lot of their produce is competitively priced) or my local indy super market, which has a very strong produce section.
When I get home from one of these every other week shopping junkets (just about the only time I use my car), I put it all away, and later enter each item I bought and the price and perhaps some notes in my database. I can look up pretty much any food item I bought, see where and when I bought it and for how much. I do that for all online purchases too, of anything.
