Door Ease Lube Stick is $4.20 right now, down from $5.73, which is 27% off. That's the lowest price in a year. It's a stick of wax you rub on sticky drawers, doors, and latches so they slide and open smoothly again. Application is clean and easy, and it works in any weather. One Cool Tools reviewer bought one, forgot about it for five years, then used it on a sticky drawer and said "it hasn't stuck since." It also works on car door fittings and trunk and hood latches.

Impresa's coffee machine descaler solution is $13.49 now, down from $18.99, which is 29% off. That's the lowest price in six months. It comes as a 2-pack of 8-ounce bottles, and each session uses 4 ounces, so you get 4 descaling sessions. It's made in the USA and works with virtually all single-serve and espresso machines, including Keurig, Nespresso, Breville and Delonghi. Claudia Dawson's colleague ran it through a 15-year-old Rancilio Silvia and a 2-year-old Nespresso Inissia and was shocked by the "discolored gunk that was flushed out." Cleaning every 3 to 4 months keeps limescale and mineral build-up in check.

The Vise-Grip self-adjusting wirestripper is $19.99 right now, down from $22.99, which is 13% off. That's the lowest price since June. It strips wire from 10 to 24 AWG automatically, so you can go from small electronics wires to heavy power wires without any manual adjustment. An adjustable stopper controls how much of the core gets stripped, and a swivel knob micro-adjusts for gauges smaller than 20 AWG. The same tool crimps insulated and non-insulated terminals from 10 to 22 AWG, plus 7-9mm ignition terminals. Kevin Kelly recommended it in Recomendo in 2019, and it carries a lifetime guarantee against defects.

Amazon Essentials' long-sleeved t-shirt is $11.10 right now, down from $14.40, which is 23% off. That's the lowest price since July. It's a plain crew-neck tee in lightweight jersey knit, with a regular fit through the shoulders, chest, and waist. The neck has ribbed trim and soft taping on the seam, and the label is printed on instead of sewn in, so nothing itches. Mark Frauenfelder picked it in Recomendo for its heavy-duty, logo-free look and the year-round warmth it gives you in cool, foggy coastal weather.

The Anker 621 MagGo Power Charger is $29.99, down from $42.99, which is 30% off. That's the lowest price in a year. It's a magnetic battery that snaps onto the back of an iPhone 15 or 14, so you can take selfies or make calls one-handed while it charges. Anker's MiniCell technology keeps the charging performance the same with fewer parts, which makes it smaller and lighter than before. It measures 4.13 × 2.62 × 0.45 inches, weighs 4.41 oz, and delivers up to 7.5W wireless. The box includes a 23.6-inch USB-C cable and a 24-month warranty.
