This may sound counter-intuitive, but after you buy something from Amazon, the first thing you should do is put that same item back into your shopping cart.
Why? If the price drops on an item you bought within the last 7 days, Amazon will match that price. If you put the item in your shopping cart, you can be alerted of price changes. This means that if the price goes down, you will know and you can contact Amazon to match the lower price.
