I need a better system to transport food purchases- I use reusable bags for carrying the whole order, I have cloth produce bags, but flours and stuff are still going in disposable bags (which I then reuse for cat litter scoopings). I buy LOTS of bulk stuff: most shopping runs are a half gallon each of black beans, rice, pinto beans, oatmeal, flour, lentils, navy beans, then also a quart each of several kinds of nuts, nutritional yeast, etc. That's a lot of big glass jars to lug to the store, and my storage containers are seldom completely empty when I restock. We've also got a few frequent visitors with food allergies, so I worry about cross contamination issues reusing bags. Bag reuse gets complicated when gluten, almonds and cashews are potential toxins. There's got to be a better way to do this. Anyone have a good system?
