Also, using a shopping service like Instacart helps me avoid impulse purchases. I make my list, put it into the cart, and don’t add anything not on the list.

It does cost more, but I actually spend less per trip because I can take my time to comparison shop and look for items on sale. “Do I need beans, or do I have some in the cupboard?” “Oh, they have that seasonal cookie I love, I should grab a box whil they are available.” If I’m not at the store, I don’t have that problem. I justify it to myself by the time saved times my normal wage being far more than I spend on the delivery fees. Reducing the bad snacks in the house is just another perk.
