It's a human nature thing I guess - buying cheap in the forlorn hope of a bargain - and many of us (including me) we never learn!
Other people come on here and ask a non-specific question as a way of getting something that bothers them off their chest.
Why do so few people ever say thank-you ?
Why do people forget to enter the make & model?
Why do people ignore capitalization and punctuation when forming their questions - is it ignorance or a desire to look cool?
You see - it parallels life in general - more questions than answers.
We will probably never know.
Good luck...
