For the next six weeks: 1) use your own containers to buy bulk goods (grains, flours, legumes, coffee, etc). 2) Buy non-perishable goods in larger containers that are not subdivided (e.g., buy the big bag of chips, rather than a big bag full of separately packaged little bags of chips). 3) Buy concentrates (of juices, cleaners, etc.) and dilute them yourself into reusable containers.
