John Ruskin – on paying too little.
It is unwise to pay too much, but it is worse to pay too little. When you pay too much, you lose a little money – that’s all.
When you pay too little, you sometimes lose everything because the thing you bought was incapable of doing the thing it was bought to do.
If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that, you will have enough to pay for something better.
