prices can vary greatly depending on the store.

Yes, I know (LOL). I have been a low-cost buyer for decades. Used to shop two major grocery stores about a block apart. Both open 24 hrs/day (at that time, anyway). Did shopping at 10pm on Sat night at one store. Bought an early Sunday edition of the paper to get the ads for the next day/week (which was less than 2 hrs away). Then browse the ads. Once I saw that I wanted something on sale, I then shopped the next week's specials at both stores.

Now, I get everything delivered. I shop online, place orders, and get deliveries right to me via Instacart or store delivery. Need more freezer space to justify Amazon Fresh, as I mostly see some of their frozen items (Stouffers) are the lowest cost of even some sale prices. Used to buy more items from them, but Fresh raised free delivery to orders of $150+ not ME !!), so I dropped them. Eligibility for Fresh was included w/Prime for orders $35+, which I could do. But $150+ is just for large buyers (i.e. families buying groceries and getting free delivery). SNAP would fit into that market very nicely. Tipping the driver would be cheaper than having to go to the store and spending a lot of time shopping with kids--especially if they don't have a car.
