Infomercials got me through a lot of sleepless nights after my separation. But I never bought one. You can find most anything all that is sold on tv in stored a few months after they come out anyway.
Never bought anything but I've watched so many infomercials just for the entertainment of it. All the real estate system scammers like Tom Vu, Dave del Dotto, etc. And Don Lapre's "Tiny Little Ads" scam stuff. Plus if you're lucky enough sometimes you can catch a half hour long "Wild Party Girls" one.
