Re-use zip lock bags unless used with raw meat, all clothes from secondhand stores or at least clearance sales at Kohls, hang clothes on a clothesline outside so I'm not using the dryer. Lots of store brand foods. cheap trac phone. Most basic TV channels.
I reuse ZipLoc bags after raw meat. I wash them out with anti-bacterial Dawn or in the dishwasher. I tried to get hubs to put posts in so I could air dry my clothes outside but said he couldn't did into the shale so he got 4 pulleys and set up wash lines on the porch. ...but now that I can't get out there so well, I guess that's okay. I bought a couple bottles of Soft Soap when it was on sale for $1 bottle and when it got halfway empty, added water. Then when it got halfway empty, added water again. Still have some after two years. I do wash once a month (only 2 of us). Whatever is left to wash waits for the next month (we have lots of clothes left from working). I still wear clothes from the '80s. I did make a partial mistake when I bought 2 lounging outfits for $9 each. Tops weren't finished at the neck which were too wide, body too short, arms too long, and waist too wide. So using tops as rags and using other tops that somewhat match the colors in the bottoms. I used to use plastic grocery bags from the store as garbage bags and in waste baskets. I do more cheapo stuff automatically, but it's such a habit i can't remember them.
