Looks like the White Van Speaker Scam guys are out in full force right now. I guess even scammers are gearing up for the holiday shopping season.
If you are approached by guys in a van asking "Hey buddy, wanna buy a set of speakers?", run the hell away.
Usually they'll present themselves as delivery drivers or installers, and by some sort of inventory error they have extra hi-fi speakers unaccounted for. They'll show you paperwork listing the speakers' price at over $1000 each, and offer to sell them to you a for a huge discount. After all, they need to get rid of them before they return to the warehouse and have to give them back to their boss.
In reality, the speakers are total shite and probably cost less than $50 to manufacture.
I know a lot of you already know about this but I thought it was worth mentioning for those who don't. It makes me angry whenever I see these speakers in someone's living room because I know exactly where they came from.
Search Google for "white van speaker scam" for lots more info about this.
