Spring is the perfect time to get clean and organized, mostly because all the tools you need are on sale! Hit up the spring organization sale at the Container Store and get your office set up for 15% off at CB2. Maybe you'd rather embrace springy pattern and color with 25% off Marimekko fabric at FinnStyle. If you're in NYC, check out a lecture at the New York School of Interior Design about the history of trends, or take advantage of major discounts during the Luceplan moving sale. All that and more after the jump.
