I don't pay much attention to deals, but the folks over at B&H sent me a pile of links (yes, I get coffee money if you use them, thank you) and it looks like there are some big opportunities if what you're looking for is among them.
I've updated the deal page as a result, so if you're in the market, take a look. Me? $600 off a Late 2014 27" iMac with 5K Retina display looks pretty interesting (my mid-2012 MacBook Pro is killing me in 4K -- for what I do, I can't use proxy files).
Happy hunting!
