Nice Hunt!

Pros:

• with nearly hourly changes in the price of different items on Amazon this is a great tool to never miss a low price anymore
• very easy to use (simply add the item and set the price you wanna pay and the app will immediately notify you when your item hits or goes under your set price)
• you can track up to 10 items at a time

Cons:

• price of nearly $3 USD (depends on how often you buy stuff on Amazon)
