It comes but once a year: The Container Store’s elfa sale.

Through Feb. 15, take 30 percent off everything in the line, which includes storage solutions for closets, laundry rooms, pantries,   garages and more. Think shelving, drawer systems, mesh baskets and flexible components to create such custom spaces as walk-in master closets, shoe closets and craft spaces.

It’s an event elfa enthusiasts mark on their calendars. Some folks plow through the closets in their homes, checking one off the list each year.

There are lots of finishes, including walnut and platinum, to choose from, as well as such options as smooth-gliding drawers. And customers at The Container’s Store new location at Christiana Fashion Center can take advantage of Delaware’s tax-free shopping.

DYI-ers can measure their spaces, order components and install storage themselves. Would rather have someone else do the heavy lifting? Installation is 30 percent off, too.
