How does your household save money?

Do you coupon, shop only online, have amazon prime, meal plan/prep, have a financial planner, use the envelope system, shop at secondhand stores, buy in bulk, etc? Due to our living arrangements falling through (Our current lease is up, and the house we were going to is having to take the previous tenant to court because they refuse to leave), so we are going to move back home for a few months and save money before baby #2 is here. I’m really good with budgeting but my mom was never into all the things listed above so I was just wondering how you seasoned wives and moms save money in your own households? Any advice is appreciated! (Sorry if I posted in the wrong place, wasn’t sure where to post.)
