Amazon offers Prime members the Belkin 12-Outlet Office Surge Protector, model no. BE112230-08, for $17.35 with free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, it adds $6.49.) That's the lowest total price we could find by $4, although we saw it for a 36 cents less in August. It features an 8-foot cable, sliding safety covers, and cable management.
