So is that niche you’re investigating really that hot?
Here’s a tool that let’s you know how a particular product is selling and has sold at Amazon.com
It’s great for checking trends and investigating if your niche is worth investing in. Crystal ball not included.
You can see what they’ve listed there or type in the URL of a particular product you’re tracking.
JungleScan.com is a free service that
* Scans products on Amazon.com to record their sales ranking over time
* Allows you to start or participate in discussions about any item on Amazon.com
Although I’m a big fan of Amazon.com, this site is neither sanctioned nor endorsed by them (they made me write that)
