I feel so proud of myself. I used my Baggu today! I have to say I felt like a darn fool because I remembered them just after the kid started putting my stuff in plastic bags and then he had to re-bag it. But my two Baggus saved probably 3 or 4 little plastic ones. My favorite thing about these is that they fold up teeny tiny and fit in your purse. That is really the key for me. I have several other reusable bags that I usually forget in my car/at home. But these are great because you fold them up and pop them back in your purse. I feel greener already!
