Actually, apparently not; his website says that he and "Michael Martin from MnTactics" are planning to give a significantly discounted class -- "$5 for paperwork" -- for up to 100 such on the 27th. In principal, it sounds like a generally legitimate promotion, although if one clicks on his signup link, there's no place to register for the $5 class at http://joepenaz.ipower.com/store/page2.html; I can't tell how they'd sign up for the $5 class, or if it's really $5 plus $3.50 for "shipping."

Still, if it does exist, even a $8.50 class is pretty cheap.
