Anker's running one of its broader sales of the summer across eufy and Anker-branded gear, and most of it lands on genuine year-to-date lows rather than the usual few-dollars-off shuffle. Discounts run 7/27 through 8/09 unless noted, with prices resetting at midnight PST on the end date.
Security cameras

The eufyCam S330 (eufyCam 3) leads the pack. The single-camera add-on unit drops to $149.99 from $219.99, a 32% cut, and it keeps eufy's usual pitch intact: integrated solar panel, 4K resolution, AI face recognition, a built-in spotlight, 16GB of onboard storage, and no monthly subscription fee.
The multi-camera kits scale the same discount up:
- eufyCam S330 2-Cam Kit: $349.99 (was $469.99) – Amazon
- eufyCam S330 4-Cam Kit: $479.99 (was $699.99) – Amazon
If you're building out a full perimeter setup, the 4-Cam Kit is the better cost-per-camera deal here.
The eufy SoloCam S340 line is also discounted, though more modestly:
- SoloCam S340 single unit: $449.99 (was $499.99) – Amazon
- SoloCam S340 4-Cam Kit: $649.99 (was $899.99) – Amazon
Robot vacuums

Two eufy vacuums are in this round. The eufy Omni C20 drops to $339.99 from $549.99, but only for one day, July 30, so this is the one to act on fast if you want it. The eufy Robot Vacuum Omni S2 runs longer, through 8/30, down to $1,399.99 from $1,599.99, though this one requires the code EUFYS2SALE at checkout rather than showing as an automatic price drop.
Audio

The Soundcore V40i gets a modest cut to $29.99 from $39.99, a solid budget pick if you just need a reliable daily pair of earbuds.
Charging

The Anker MagGo 3-in-1 Charging Station drops to $79.99 from $109.99, covering phone, watch, and earbuds charging off one station, a straightforward pickup for anyone tired of cable clutter on a nightstand.
The bottom line
Most of this sale runs 7/27 or 7/28 through 8/09, except the Omni C20 (July 30 only) and the Omni S2 (through 8/30, code required). If the eufyCam 3 kits are on your radar, this is a real discount rather than a token markdown, worth acting on inside the window rather than waiting for a deeper cut that may not come
