I try to adhere to my grandmother's depression-era mantra: Use it up, wear it out, make it do or do without. "Try" being the operative word!
I only use my checking account for paying bills and buying groceries. After my bills are paid, I get cash, and when the cash "allowance" is gone, it's gone until the next deposit to my account is made, one on the first of the month and one around the middle of the month.
Definitely Aldi for groceries! The Goodwill store is a treasure trove for a lot of things like clothes, small appliances, dishes, pots & pans, even jewelry. I only started going there because my g'daughter loves it. She'd want to go "Goodwill shopping" and would invite me to go along. Dang! They have clothes that have never even had the original retail tags removed. Shopping for clothes there requires a lot of time and a lot of patience, but hey! I'm retired, remember? Nowhere to go and all the time in the world to get there. LOL
Aunt Bea, "dead bread" store! We had one in the small town where I used to live, but there's not one close to me here. If wishes were horses...
Going to farmers' markets close to the end of their day can yield some real bargains on fresh fruit and veggies.
There are probably lots of others, but I can't think of them off the top of my head.
