As I arrived home from a brief trip Thursday night, I had to navigate a small pile of brown boxes—the results of some Amazon Prime Day shopping. Prime Day 2019 may be in the rearview mirror, but one discount is not: Ars is extending the discount for new Ars Pro and Ars Pro++ subscriptions. If you subscribe in the next few days, you'll receive 20 percent off the regular price.

Here's what you get with the $25 $20 Ars Pro:

No ads: If you're logged into Ars, you'll never see an ad

No tracking scripts: Every last one of those scripts disappears for Ars Pro subscribers, with the exception of those from objects embedded in individual stories like videos from YouTube and tweets from Twitter

Full-text RSS feeds: See the whole story and never leave your RSS reader

Subscriber-only forum access: Sit back, relax, and vent your geek angst in The Lounge

Article PDFs: Read our great long-form content offline

Classic reading mode: Read Ars in the old-school way

Ars Pro is compelling on its own, but for $50 $40 Ars Pro++ offers all of the great benefits of Ars Pro, plus:

A subscriber gift: Currently a YubiKey 4 two-factor authentication device, a $40 value on its own

Clean-reading mode: it's a layout optimized for the Ars Pro++ ad-free experience

A coupon for 20% off additional YubiKeys so you can help your friends and family be smarter online

Producing quality journalism has always been job one for Ars, and advertising no longer pays the bills in this industry. Use the coupon code DIES PRIMUS MMXIX to support the mission of Ars with 20% off your first year's subscription.
