Has anyone used The Tax Club?

The Tax Club (www.thetaxclub.com) contacted me today after I formed an LLC with LegalZoom.com. They had a lot of information about taking advantage of tax loopholes and seemed like a nice convenient service until I tried to get off the phone with them. I got trapped in a hard sell that felt exactly like someone trying to sell a warranty. Sounded like their service started at $1500.
