Rebates and whatnot, plus an inflated trade, often gets you near 50% for boxes. You often have to wait for that, or the "rock and roll" truck. "Discounts" for financing also apply, like finance 3k, get $300 off. Finance it all, get your discount, then make your down payment the first week. I got 90 days deferred interest on my locker, still got the credit for "financing", and paid no interest.
I got offered 2 84" epiqs when looking for my locker. My 1033 and Single bay KRL top/bottom I got on craigslist for $700, +10k, got whatever pair of 84s I wanted. I chose to pass for various reasons, YMMV. The list on those boxes was like 32k or something stupid like that.
When I got the 1033, it was $5600 tax and all - Traded in my top/bottom KRA I got for $1800 a few years earlier. List was like 12K.
