Has happened here in the UK too - a TV programme found the warehouse reselling them and got a job to see the training. I think the speakers basically cost £30, the bloke running the business needed a minimum £200 cut and the rest could be kept by the salesman. Everything was legal except for the wattage specs on the box, apparently they should have specified PMPO as that's what they quoted.
The funniest thing was some student paid £650 for set on the strength of the sales guy telling him they were worth £2k!!!
