Froogle is now including products from eBay stores, something it has not done in the past. Conduct a search in Froogle on store:ebay, and it will display all products in the Froogle index from eBay stores.
CobaltLady from DigitialPoint Forums felt that this is a good thing, "Ebay store items will be in the upper tier." Respree, responded "To a certain extent, I think its bad. If a merchant has both a website (and has submitted a feed directly to Froogle) and Ebay store, duplicate listings will occur (thus littering the Froogle SERPs)."
However, there are dozen's of sites that contain the same exact product and have slightly or similar pricing and information. For one owner to have multiple store fronts is not abnormal at all online, or even offline.
