Groceries are the easiest big number to shrink because you touch it every week. Over three months of tracking, we cut ours by almost a third without anyone at the table noticing a downgrade. Here is the system that did it.

Shop your kitchen first Before writing a list, we spend five minutes taking inventory of the fridge, freezer, and pantry. Half of grocery waste is buying things you already own. Building meals around what is about to expire alone saved us roughly ten percent.

Plan meals around sales, not cravings We check the weekly flyer and the markdown shelf, then build the menu from whatever protein is cheapest that week. Chicken thighs on sale beat a fixed recipe that demands $14 salmon. This is the single biggest lever.

The price book trick We keep a short note of the lowest normal price for the twenty items we buy most. When something dips below that number, we stock up. Without a price book, a sticker that says "sale" can still be a bad deal.

Cut the convenience tax - Pre-cut produce costs two to three times the whole version - Single-serve packaging is almost always a markup - Bottled drinks add up faster than any other category

What we did not do We did not switch to a worse diet, clip hundreds of coupons, or drive to four stores. The savings came from planning and timing, not suffering. Pick the two tactics here that fit your life and ignore the rest; even those will move the number.
