Not only will you save hundreds of dollars a year using the info on this site, Dave the owner, went out of his way to speak with me on a Sunday morning to solve an issue I was having. You cannot ask for more than that which is the reason I just became a lifetime member. I would encourage anyone who regularly uses this site to do the same, seriously you save many times more than the donation each season in chemicals alone. Not to mention all of the other great advice from all the other users.
I have no affiliation with the site other than I became an avid user this year. If my suggestion violates a forum rule, I apologize. You cannot find better advice or customer service anywhere.
