Unless you're building robots or editing blockbuster films, there's a decent chance that you have been paying for -and hauling around -much more computer than necessary. If you primarily work with office suites, stream favorite entertainment, browse the internet, or take online courses, then an ultralight laptop can do all you need.

A 13.3" Apple MacBook Air would be perfect, except they tend to be a little pricey. That's what makes a refurbished model such a bargain. This 4th of July, you can get all the great features of a powerful featherweight laptop at a much lower price. But only if you use code JULY20 before July 5.

This MacBook Air weighs less than 3lbs yet has all the power you need to work and play. With a 7-hour battery, you can do both from anywhere. It has a 1.8GHz Intel Core i5 processor and 128GB of fast SSD storage with 4GB of RAM. The 13.3" widescreen has a 1440x900 resolution and pairs wonderfully with an Intel HD 4000 graphics card. As a result, you can enjoy your content with superior clarity, and your videos will stream smoothly.
