Amazon does not appear to be struggling to keep it's ebook revenues up, so it looks like you do not speak for the bulk of the market.
You are of course free to 'move on' for any reason you like. You can move on because the cover image clashes with your living room decor.
To me, that would be just as valid a reason as arbitrarily and presumptive deciding that a product is priced too high, not because of the value that product offers you, but only by comparing the price to a different product.
If you wanted to see a movie in a theater, would you refuse to buy a movie ticket if the ticket price was higher than the paperback price for the novel?
