I'm fully off of the paper ads.
I create my online list, and streamline the "in store" process.
I basically only shop at Jewel, Aldi, Tony's, and my lil fruit market down the street. All 4 places are a stone's throw away, and I can run in and out during the day while I'm working at home, so crowds aren't really a thing, except at Jewel, since they kinda limit their payroll on cashiers during weekdays - understandable.
My m.o. is to check the online sales flyers on Wednesday (thanks, Jewel, for letting me preview on Tuesdays!) Then I can cross ref everything and figure out a loose menu for the week, or figure out what to pull from the freezer because there's something decent to buy to throw in the freezer to replace it. I also check Peoria Packing and Shop&Save, but those are rare visits unless something is strikingly worthy.
After cross ref, I have a list of each joint's best items that we'd actually need or want. The whole process takes about 20 minutes, and then when I'm in store, I can just have complete tunnel vision, but I can also spend a few minutes looking at clearanced oddities. One good thing that's come out of it, is that I can share my list with that one lady I'm married to, and I can send her to a store and she won't come home with a rock hard avocado, a frozen goose, and 4 sleeves of leeks instead of the gallon of milk and loaf of bread that we needed. But that's kind of a side note.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
