Pioneer AVH-4200NEX & Kenwood KH-KR900 $400 AR + Free Shipping at Sound of Tri-State
I missed out on the last deal for $400 at Newegg but recently found that Pioneer is having a $100 rebate on a few of their receivers. Rebate is valid for purchases between May, 19 2017 to Oct. 1, 2017.
Sound of Tri-State is selling different packages with the receiver, but I didn't care for the headphones and bought just the receiver through Amazon. Rebate terms states that Amazon.com purchases are not valid, but you'll have to request a store receipt by emailing your order number to Sound of Tri-State.
