Tote bags! We pick them up at every conference! Some are great for the grocery store so you don't need to waste getting a plastic bag (which will just end up in a landfill). Those I keep in the trunk of my car so they are always with me when I stop for shopping. Those that are not suited for that task can be MANY in number. And how many do you really need?? Pick out 2 or 3 that give you pleasure when you remember the occasion, and are also good for toting to the gym or a one night overnight. I keep mine at the back door which I use to enter the garage. That way they are available to me as I am heading out and might have my hands full. The rest simply donate as there are others that could certainly use them! If they are worn, ripped or dirty, ditch!
