If you find an item on one of your favourite online retailers websites that you would like, but are not in a rush to own, you can set a price in PIWoP that you would like to pay for it. PIWoP tracks it for you and when it drops due to a sale, promotion or clearance, PIWoP tells you! It can cope with as many sites and items as you want to track. There is no monthly charge or commission to pay, just sign up for the small annual subscription that suits you. There is even a free 'Tester' option!
