Have you downloaded any of those over-price ebooks recently? A great many people are writing fluffed up ebooks that have little valuable information, but they sell for $47 or more.
The majority of these fluffed-up monsters would be reduced to just a few pages without all the needless, page count expanding filler.
I bought a high priced ebook from a famous AdSense guru, the guy that says he makes $30K a month from AdSense. After reading nearly 200 pages, all he said is to make the AdSense ads look like they're part of your website instead of looking like ads.
Of course, he couldn't charge the big price if he just came out and said that. Nobody would be happy paying his price to get a 5 or 10 page ebook.
The new thing in ebooks is 'short and sweet' - just pertinent information, minus all the extraneous garbage you don't need. Refreshingly short ebooks that give you the knowledge you seek without making you wade thru page after page of irrelevant ramblings. Prices so low that it's probably pocket change for you.
How much? Do you like seven dollars?
