They were 10% off in January. To my knowledge the sale is over now. But I bought mine from black sheep10? On pirate. He wasn't the cheapest, everybody I contacted was within about $100 of each other on 4 total. But all the threads I read and looked at he was always the first to offer help and tech support with questions, and threads he didn't post in people referred the op to him with their questions.
I was $2400 on 2 14 and 2 16.
