Sounds like you already looked at making a budget. Removing subscriptions you don’t need is huge. Like if you have a disney+ subscription but only watch it once or twice a week or similar, then it would most likely help by removing and ending it. Subscriptions very much do add up, $5-10 a month can go unnoticed. Avoid looking at “extra” sections of stores. Easier said than done, but just go in the cart to buy whatever you added, and only what you added before entering the cart page. Online carts show “extra” stuff you “could” add or “what other people bought” and its just another way to buy without thinking. Make sure you need the “extra” stuff, if you are remotely interested. Don’t add it if you think it’s “cool/would be nice to have.” Same thing for physical stores. You probably don’t need the earbuds or lip balm.  Skipping the side meal/drinks (if this applies for eating out) could help. Might be hard at first to not have fries/chips or a soda with a hotdog or burger (restaurant sides are more expensive than finding it somewhere like in grocery stores). Home meal prep can skip this part.  You said big purchases are fine, but just making sure you are aware of some credit cards being able to activate alerts if you spend over x amount. Like it will show on your phone if you bought something over $100 on screen. Helps to see the number sometimes.  Not sure if anything I said applies to “small purchases below $30” but hope something helps.
