No Manufacturer can tell a dealer what to sell the product for ...period...if they do they are breaking the law, in fact I do believe it was the hifi bus that made this so, I think both B&0 and Pioneer were charged with this in the 70s....anyway If a ML dealer says he "cant discount" because the manufacturer said so...is in stric violationof the law....sure you can ask for a discount and you will probably get one...the more you buy from a store, probably the more they will take care of you on both price and service....BUT they need to make a profit to stay in business and 10-20 percent over cost doesn't cut it...my guess is on any speaker line you can get 10-15% off and everybody is happy
