Dewalt Days is live at Lowe's, and you can save a pretty penny on tools, batteries, and even air compressors through the end of April. The prices are very competitive with retailers like Home Depot and Ace Hardware.
Another great way to save on items and get freebies at Lowe's with MyLowe's Rewards. It's a completely free membership. I've seen freebies on paint samples and flowers.
