“There is almost nothing in this world which can’t be made worse or sold cheaper by someone, so that people that only care about something’s price are an easy prey of those plots.
It is not wise to pay too much, but it is even worse to pay little. When you pay too much, you lose some money; that is all. However, when you pay too little, sometimes you lose it all, since the object you bought cannot carry out the function it was intended for.
The law of trade forbids receiving high quality for little money.
Should you accept the lowest offer, you have to calculate the risk you are taking. Once you have done it, you will enough money to pay for something better”.
ohn Ruskin (1819-1900) English thinker.
