It can be inappropriate to price things according to time taken. If you set yourself a charge at dollars per hour you may be disappointed. You could say, "my time is $50 an hour, I spent 100 hours on this project so it's worth $5000. I expect 50 sales so the price is $100". But the buyer doesn't look at it that way. The buyer doesn't care how long you spent, but only how suitable the product is for (a) use, and (b) impact on purse. I might look at that product and conclude I have better things to spend $100 on. The fact is, that it's a buyer's market, and the expectation of the buyer sets the price. It's no use fighting against that.
