The M18 Rocket Dual Power Light is $179.00 right now, down from $226.86, which is 21% off. That's the lowest price in 90 days. It's a telescoping tower light that runs on cordless power, so you can light up a job site or any spot where dragging a cord isn't practical. Derek "Deek" Diedricksen picked it for his treehouse building, where corded tools make climbing a hassle. The light is lightweight enough to haul up with you but still "powerful enough" to do the job. Milwaukee makes it in the United States, and it has a low battery indicator so you know when to swap packs.

The ACTO Paper Trimmer Commercial Cutter is $83.22 right now, down from its typical $101.20 over the last 90 days, which is 18% off. That's the lowest price since July. It cuts up to 15 sheets at once, and it handles paper, film, and photographs. A perpetual edge self-sharpening system keeps the blade sharp, and the heavy wood base keeps the whole thing stable while you cut. Our reviewer used it to saddle stitch countless booklets and newsletters and to bind a 1990s zine. A safety guide and latch make it usable in school settings.

Simply Saline by Arm & Hammer is $3.92, down from $8.39 (Amazon's list price), which is 53% off and saves you $4.47. That's the lowest price since July. Kevin Kelly recommended it in Recomendo as a sterile, pressurized aerosol mist that irrigates your sinuses without the infection risk of a traditional neti pot. He also said it clears up phantom smell symptoms. The 4.5-ounce can is made from three ingredients: purified water, salt, and Arm & Hammer baking soda. It has no steroids, fragrances, or dyes, and it's drug-free.

The Laptop Bed Tray Table is $38.97 right now, down from $49.99, which is 22% off. That's the lowest price in 90 days. Mark Frauenfelder bought this small desk so he could work in bed and on the couch. The height and angle both adjust, with five heights from 9.4 to 12.6 inches and four angles up to 36 degrees. Rubber stops along the bottom edge keep the computer from sliding off, and the 23.6 by 13 inch top is made of wood. It folds flat to 1.8 inches thick. He and his wife also use it to watch movies in bed, and he found his typing accuracy was better on it than at his regular desk.

National Douglas Fir Tree is $206.99, down from the $329.99 list price, which is 37% off. That's the lowest price in 90 days. It's a 7.5-foot Dunhill Fir with a 59-inch base and hundreds of individually crafted branch tips, so the branches come out full. Mark Frauenfelder wrote that once it's covered in lights and ornaments, "you can't really distinguish it from a real tree." The hinged branches drop down for setup and fold back in for storage, though you'll want to set aside 45 to 60 minutes to shape the tips. The needles are hypoallergenic and fire-resistant, and it comes with a durable metal base.
