On Amazon right now you can get this SODIAL(TM) Strawberry Folding Fold up Reusable Compact Eco periodic duty Recycling use Shopping Bag for only $1.16. Shipping is FREE but it is coming from Hong Kong, so it might take awhile. I gave these out as teacher gifts one year and got great feedback!
Thanks A Frugal Chick!
