Upgrade your door to Anker’s eufy FamiLock S3 Max Matter smart lock for five entry methods + 2K video at its $280 low

Through its official eufy Amazon storefront, Anker is offering returning Prime Day pricing for Prime members on its FamiLock S3 Max Matter Smart Lock to $279.99 shipped, which matches the price we’re seeing direct from the brand’s website. Normally going for $400 at full price, most of the discounts we’ve seen in 2026 have dropped the costs between $350 and $300, with some occasional falls lower to $280, including during Prime Day last week. That pricing is returning here, giving you a $120 mark
