That's total B.S. I tell you. If you do offer such product - it only means you'll get fewer refunds, may be even no refunds at all but you will not necessairly make money... unless you are a GREAT marketer who can rank #1 out out 1,000,000,000 results on Google, or if you somehow succeed to hook up with the known boys, like Filsame, Kern, Silver... who will promote it to their 1,000,000 lists.
Some of the GREATEST info products I ever purchased were only selling a few copies a month... at $30-$60...
AMAZING Content is not enough... Please stop saying it is.
My frustrated rant for the day.
