One of our treehugger friends shamed us when we did a quick run to Rite-Aid and popped out carrying a plastic bag. After a meaty lecture about how the environment is peeved at the human race and how polar bears are drowning, we decided to pick up a set of these Amazon Envirosax nylon bags. The Amazon Envirosax Set (Set of 5) is available at Flight001 for $42, or individually for $10. Our main obstacle with the nylon bag theory is that we do shopping in bulk. Once a week, we hit up the Ralph's or the Trader Joe's and stock up on the staples. And quite frankly, these new reusable shopping bags seem to be built for the city life; or maybe the European way of life which (in our minds) includes quaint market stands that offer wonderful organic fruits and vegetables. We're making an effort to bring these Envirosax bags with us everywhere. Luckily, they're compact: each bag rolls up in a tiny ball with a handy snap, making it extremely easy to chuck in our purse and whip out when we're needing to bag up our purchases. Oh, and here's another good thing we've found out on our last grocery trip: one nylon bag holds the equivalent of two supermarket plastic bags.
