Didn't have to buy anything extra at all.
I first ordered 1 XP1000 and after telling my brother about the deal he ordered the second one at the same deal.
I called this dealer to and the guy was kind of an ass. Asked him about this price and he said it was but I had to purchase $2,000 in accessories. I said I didn't want any and he said I could pay full MSRP then. I said no thanks.. Lol
Not sure thats legal. But doubt they get called on it.
Back when i worked in retail a big box store i worked out tried to make people do that on certain "hard to get" electronics. They ended up with a big fine and paying thousands to customers.
Either way. I wouldnt buy anything from that dealer if that was the case.
