Oh yeah, I definitely make coffee money when you click on one of my links (and it doesn't cost you a dime), but I'm posting these links because these really ARE big deals.
Take for instance my 2014 Camera of the Year and still a favorite that I use all the time, the Sony a6000: B&H is quoting $398 for the body, which is just sick good (normally $548, for real). Amazon is quoting the same. That's more than a 1/4 of the usual price, and Sony is going to continue selling it. At this price, I would have paid $198 for it back in '14 when I applied my Vimeo Pro $200 gift card. If you don't need 4K or high frame rates, this is by far the best way to get into the Sony mirrorless hybrid world.
Or the Panasonic GX85, a camera I'm evaluating right now. It's priced closer to the a6000 but spec'd closer to the a6500, and I'm really liking it. B&H is offering $100 off the usual $798 with kit lens along with some other stuff. Same kind of thing over at Amazon. Not as deep a discount as the a6000, but if you want into the micro four thirds system, I can't think of a better entry point at the moment.
I'm looking for some hefty discounts on Sigma's Art lenses, but so far, no one's offering discounts like these. Still, if you are interested in other lenses in the Sigma line, there are some 15% or so discounts happening (including their 150-600 zooms), again from B&H.
Here's a link to all of B&H's holiday deals, though I haven't gone through them.
Ditto with Amazon:
