Sometimes we are lead down a path to make purchases that are not necessary, or in fact worthless. I have done so many times. I do not wish to slander or hurt some one else's business outright, but always ask in a forum [b]Before[b]you purchase. You are doing that now, so you are off to a good start.
Just ask if anyone knows of a product or service and of it's value. Get the
opinions of those who know from their experience and go from there.
Believe me, you will still make some mistakes but will be spared some also.
