Amazon assigns a ASIN (Amazon Standard Identification Number) to each product they sell. There are two ways I’ve found to look them up. One is to visit ASINLookUp.com and use their free lookup tool. The other is just to look at the URL in your browers when you navigate to the item on Amazon.com. The URL will have either a “…\product\83726684\…” or “…ASIN\9383678\…” in it. This is the ASIN and can be used to identify the product in question. Try pasting it into the code you are using and you should see what you are expecting.
