There was a promotion yesterday directly from Razer (I think it was called a CES special) - where peripherals from Razer.com were 50% off but see fine print.
I bought a bunch of gear a week or two before (huntsman elite, nari ultimate wireless headphones) so I didn't bite but I filed the coupon code away in case I decided to use it later. Then I noticed the fine print - only good for the next 24 hours ...
