There is scarcely anything in the world that some man cannot make a little worse, and sell a little more cheaply. The person who buys on price alone is this man's lawful prey.
It is unwise to pay too much, but it is even worse to pay too little. If you pay too much, you lose some money, that is all. If you pay too little, however, you will sometimes llose everything, as the thing you bought cannot do the intended job.
<boring comment>You can do some optimization. play with prices a bit. sell at a different price in different countries. see which generates the best profit. You will find out that overpricing is bad. under-pricing is bad because it leads to customer loss of trust in your product and even sometimes to low quality products. The best price is somewhere in the middle.</boring comment>
