Just hopped on to my Arlo app on my phone to check an alert notification and received a pop-up stating that the 30-day storage subscription is temporarily 50% off, for $5/month (normally $10/month).
This includes 30 days of cloud storage (versus 7 days with the free subscription), up to 10 cameras, and unlimited support.
Not sure if this is new subs only or not, or if this is a targeted offer. May be worth checking your app if you use Arlo to see if this is an option for you. Looks like it applies to all Arlo products.
