He also makes a good point on the air that some people might not have known; Price Protectr works both for online and in-store purchases. Just hold on to that receipt and take it to the customer service desk if the price drops. They'll refund you the difference with no questions asked. Keep in mind that in-store and online prices might differ, so give em a call and double check the price before you drive all the way out there!
