I took a chance like most contractors. I bought $20 in credits, since most requested quotes are only 3 or 4 dollars. I actually sold my first one! I thought "this is going to be great" Not so fast my friend! I have used almost all of the rest of my credits and have not sold 1! I only had 1 other that requested a quote for gutters and guards. Of course, the customer wants you to just go by, take a look and leave a quote in the mailbox! So, not only a waste of money, but a huge waste of my time. I will not be buying any more credits. I'm done
