I have been very good about remembering my reusable shopping bags lately and plastic bags hardly ever make their way into our house. I was still collecting the occasonal plastic produce bag though, so I ordered these reusable produce bags from ecobags.
They are super light so they don't affect the total weight of your produce. I used to only have to remember my shopping list when I went to the grocery store. I am accumilating more and more things I have take with me!
