Hi- This is cut and paste from ebay site. Unless I am totally mis-reading this, this is a great money saving device as well as huge time-saver. If anyone understands or interprets this differently, pls. let us know.
List multiple variations of a product including color and size in one 35¢ listing!
* Save on listing and photo fees
* List more in less time
* Manage inventory right from your listings
* Price each variation separately
* Great way to cross sell
* Get exposure for more inventory
Here is listing link from the Bay:
