Buy in bulk
It can be cheaper to buy things in large quantities and bulk-buying also reduces the time you’ll spend in the grocery store aisle on subsequent trips. Buy dry pantry items like brown rice, nuts, quinoa and beans in bulk. Beans last for a year, while brown rice keeps for at least six months if stored properly. Other great, healthy, items to buy in large quantities when on sale? Pasta sauce, canned tuna and low-sugar, high protein granola bars.
