By now, you’ve probably gotten into the swing of bringing reusable bags when you go to the grocery store — that is, when you remember. This handy tote system from MY ECO simplifies the whole proposition. Three giant reusable bags are tucked into a zippered sack, and each is designed to pack your groceries securely — one is insulated for refrigerated and frozen goods, and another is padded for glass bottles. They contain enough space to hold a week’s worth of groceries for a family of four. $25 a set at www.getmyeco.com.
