The question has arisen on other threads about whether or no you can get 10% off the whole sale.
You can if you buy a TS saw & MFT table or a TS saw & CT dust extractor. The combo's normally give you 10% off the table or the dust extractor. With this sale, you get 10% off both.
It occurs to me also, that if you buy the Parallel Guide Set, as opposed to buying the separate Parallel Guides and the Extensions, you already save about 10%. If you buy the set in April or May, you get 10% off of 10% off.
