The dea. through Groupon to get 30 (or 20 in NYC) classes in your area for only $20 is total bs. The Groupon promotion doesn't make it clear you rhave to go through an elaboratge registraton on their website--and the website is unnavigitable. Plus--it won't let you actually do anything for two days after your register. It will, however, play over and over an awful little video from Adele Fridman, sometimes two at almost the same time, so you get an echo effect.
I can't tell if it's a scam or just the worst website I've ever seen.
