It costs my store 2 cents for a plastic bag, whereas a similiarly sized paper bag is a nickel. Not a big difference, but it adds up quickly.
I use plastic because they have more potential for re-use in my household. We have cats to clean up after, and they're indoor cats.
Hi Kirk...
Paper or plastic...the best solution is to bring your own bags. Supermarkets in France have sturdy ones you buy for a small amount, they mark the date and when they wear out they GIVE you a replacement
That's a good point. Though sometimes my life doesn't reflect that amount of organization, in terms of deliberately setting out to a specific store, as opposed to just running in on an ad hoc basis.
