Thermaltake Crazy Sale: up to 99% off after MIR and free shipping.
Several of these item are free after mail-in-rebate, but the website doesn't show that (the e-mail did).
I believe that all of them have mail-in rebates, but I haven't verified that.
However, if you open the product page, you will find a .pdf for the rebate, valid from 10/20/15 to 10/30/15.
Free shipping with code PF9390.
Here's some example of free after MIR products:
Gorb II Speedy (not quite sure what this is )
Dracco Signature headset
2800mAh Battery Power Pack
Thoughpower 480W power supply server edition
... and more
