Remember this? You can enter your Amazon purchases and be alerted to price drops within the next 30 days, and then collect your refund.
Now you can do the same thing with Amazon and the following stores: American Musical Supply, Backcountry.com, BestBuy.com, BestBuy.ca, Bike Nashbar, Circuit City, CompUSA, Cooking.com, Costco, Future Shop, Jenson USA, Office Max, Sears, 6th Avenue Electronics, Staples.com, Staples.ca, or Target.
Enter your item info and then wait for the alert that the price has dropped. Easy. I love the internet.
