Available for in-store pickup only, Office Depot and OfficeMax offer the APC Back-UPS NS 600VA 8-Outlet UPS Battery Backup, model no. BN600G, for $29.99. That's tied with our mention from last Thanksgiving as the lowest price we've seen, and it's the best deal now by $35. It features up to 13 minutes of backup power at half load, four outlets with battery backup, four surge-protected outlets, and low battery and overload alarms.
