Froogle is good for being free, but for the thousands of items that I list on there, I rarely get a sale, even with good pricing it's rare. I think you have to have over 100k items to really see any business from froogle. Right now I like about 20,000 and I rarely get a sale from froogle. Maybe 1 in 2 months. I get a little bit of traffic which is nice though and I'm sure there's some call-in sales. But hey, it's free so might as well use it. I think some people just make dummy sites and list all of their products on froogle, same products but from a different domain, so they can spam the database.
