No plastic in grocery shopping
1. I take cloth bags of all sizes to pack my groceries in. I buy bulk as much as possible - rice, spices, nuts, beans, salt, sugar, coffee etc.
2. I refuse to buy fruits or vegetables wrapped in plastic. I don't buy berries, cauliflower, salads in plastic containers, chips, pasta - if it is wrapped even in an inch of plastic, I do not buy it.
3. I am wlling to spend some extra money to buy meat from the butcher or co-op wrapped in paper. I do not buy meat or fish wrapped in plastic.
By focusing on this and simply refusing to waste food, I have significantly reduced the amount I spend on groceries. My trash bin is now every other week and I save money there also.
