Today only: Save up to $820 on 2018 MacBook Pros

Amazon-owned Woot is also knocking up to $820 off refurbished Mid 2018 15-inch MacBook Pros during its daily flash sale, with the greatest discount found on the upgraded 2.6GHz, 16GB, 512GB, Radeon 560X model in your choice of Space Gray or Silver. This configuration, which is now $1,979.99, features a faster processor, additional storage and upgraded graphics over the standard model.

Refurbished by Apple but without the Apple warranty (and packaged in a generic white box), each of these configurations comes with a 1-year Woot warranty for added peace of mind. To put the savings in perspective, it would cost at least $320 to $520 more to purchase a 15-inch MacBook Pro in new condition, according to our 2018 15-inch MacBook Pro Price Guide. And in the case of the upgraded model, this matches the absolute lowest price we've ever seen.

This offer is valid through 10 p.m. Pacific Time on May 15, or while supplies last. Woot's Apple deals have been known to sell out early, so don't delay if you want to take advantage of the discounts.
