The Container Store takes 30% off Elfa products during its Elfa Sale. (Discounted prices are as marked.) Even better, it also takes 30% off home installation. That's tied with our mention from a year ago as the best flat discount we've seen from The Container Store and yields several price lows. (For further comparison, we saw up to 50% off a wider selection of items last spring.) Choose in-store pickup to avoid shipping fees, which start at $8.95.
