Tormek doesn't tend to do sales, but they do special rebates and other offers.
I bought mine when Woodcraft was having one of their one day 15% off everything sales; it's not exempt, unlike Festool, etc. Tormek was also running a promo where you got the knife sharpening jigs for free as a rebate, so that worked out to be a pretty good combo deal for me on a new T7!
