For its members, Costco offers the Siemens VersiCharge Gen 2 30-Amp Indoor/Outdoor Electric Vehicle Charger for $399.99 with free shipping. (Non-members pay an additional $83, so it's better to get a 1-year membership for $60.) That's $99 below our May mention and the lowest price we've seen. (It's the best deal now by $99.) It features an LED charging light, 20-foot cord, and charge delay button.
