I have noticed that most of the new WordPress themes are selling nowadays for < $29. My question is - isn’t it going to hurt marketplace in a long term? The reason is that customers will expect to get a WordPress theme for these type of prices. And as you see most of the new items that were selling good for $19-$29 are unable to generate any sales with a proper price. So if you are a customer - what is the point for you to get to a marketplace and purchase a $59-$69 theme if there are hundreds of new fresh items priced at $19-29.
And authors should take a blame too, by selling a theme for $19 you are basically giving it away for free and the only one who is benefiting from it is Envato with their fixed fees. You basically end up developing a theme for couple months, then selling hundreds of copies for $19 while making very little from it and then you end up with hundreds of customers that you have to support for free, and the minute you raise the price - your sales stop.
