Perfect for cold winters (and hot summers), JC Whitney has the Cheetah Four-Button Remote Car Starter on sale for $49.99. This device allows you to start your vehicle and either warm it up or cool it down for up to 24 minutes and from up to 500 feet away. The vehicle will start but cannot be driven until the key is connected to the ignition, so there are no theft worries. Plus, if you don't already have keyless entry, the Cheetah can be programmed for that as well. I have a remote starter and use it constantly in the winter. Shipping is $8.99 and tax varies by location. If you're spending over $100, be sure to use $20 off coupon code DADHKX7 (expires 12/31).
