How do I recycle the plastic mailer that you shipped my books in?   Unlike some plastic bags which are only partially recyclable, our bags are made from 100% recyclable plastic. Check with your local recycling collection agency for information about including Thrift Books mailers with your normal curbside pickup. Even if you aren’t able to mix them in with the rest of your recycling, most grocery stores will accept our mailers along with standard plastic shopping bags.
