As one of its daily deals, Best Buy via eBay offers the CyberPower 8-Outlet 450VA UPS Battery Backup for $34.99 with free shipping. (Fry's has it for the same price via pickup.) That's tied with last month's mention and the lowest price we could find by $9. It features 890 joules of surge protection, four outlets with battery backup, EMI/RFI noise filter, and a USB port. Deal ends today.
