- Add the product you want to spy on to your shopping basket
- Go to the cart page
- Edit your quantity, select: 10+
- Enter 999 units and hit the update button.
- Amazon will now show you how much product is currently in stock for this product.

For each day it will do the 999 trick for the products you like to track. Then it will show you this overview where you can see exactly how the inventory levels changed for a particular product.
