Not to mention that the grocery stores that are well located are usually more expensive. The cheaper options exist in less number and so it makes it less convenient or sometimes not possible at all to get to on a normal work day.
You can save a lot of money that way.
And I’m in Europe FYI.
Yes that’s how it works. You save some money and spend it in other shit.
Also I don’t have a car just so I can go get groceries. I have a car for a multitude of other reasons and I can get groceries. Driving 5 mins to a supermarket has an insignificant cost, and if that supermarket is cheaper then you can save multiples of that.
Regarding the stuff expiring, that’s just your experience. I have the opposite. There’s plenty of non perishable shit that I can get when it’s on sale because I can carry a ton of it if I came by car. Meanwhile if I go shopping by foot and I need laundry detergent I’ll just have to get whatever they have at that time. You can save a ton of money like that.
For easily perishable food yes buying regularly is better but that also means a ton of wasted time going to the supermarket very frequently even if to get only a few items.
