Take a look at what other companies are charging for PDFs of books. Wizards prices are not out of line with the current market.
So? That just means too many people are willing to pay too much for PDF's. Besides, I do know. There are some Green Ronin PDF's I am willing to buy, Goodman, and a couple of other companies.
Most companies are charging too much, which is why most of the PDF's I have were either free, or were offered up in some great ENWorld sales.
I have not bought a single Necroamncer PDF, for example, and I have been accused of being a Necromancer fan boy. The only one I have come close to buying is one I got "free" for pre ordering RA:R.
The bottom line is PDF do not cost the same to offer for sale, and does not even have to go through a tier or three of resellers if they want to host their own PDF site from which to sell them. Even then it only goes through one, and I doubt they charge 20 to 40% of the retail price to do so.
PDF's do not require printing, they do not require storage in warehouses or in stores, they do not require shipping via semi's to get to their points of sale. They do not require people to load, unload, box, or unbox at these various stages.
So to say that charging greater than 50% of a books retail is fair is in my view a lie. I am a firm believer in "triple key" pricing, and PDF's, as well as far too many companies, have been going far beyond this for far too long.
So I wish people would start to realize that companies making too much of a profit off of you is still wrong, and start refusing to buy such items. Too many people seem to think that a company trying to maximize their profits, etc... is a good thing, and is sufficient justification to over charge for their products and take peoples hard earned money.
In my book, this is unacceptable, so I do not buy PDF's, I do not buy software through retail outlets, and so on. IT is not OK with me for a company to suck as much of my money out of my pocket as they dare to get away with. In my book getting more than 200% margin of profit is in the realm of greed, not fair profit.
So when I find products that have such a high mark up I do my best to not buy them.
