I had an “opportunity” to be tried on this very common scenario. Frankly there are very few opportunities of getting some thing without effort or getting a really good item at a very low cost. Some years back,I bought a second hand car at a “give away price” . It looked good and totally clean. On seeing it while I drove, my workmate thought it was new and would not believe that it was a second hand vehicle.
The car gave me the worst problems I have ever encountered with a car. I probably spent half the buying price making repairs on it.
It may be any thing; a house, an educational course, anything! Please don`t get me wrong. There still exist good affordable priced items/services. One just has to be extra careful.
Many examples can go for people. Use extra judgement when dealing with extremely generous strangers or cunning individuals.
Do you have any experiences with things being so good to be true? Let`s learn from each other.
