Had something like it a while ago, it is just far to difficult to manage and co-ordinate on a regular basis. We do/did have special savings and coupon codes in the newsletter; there has been free shipping, 10% off, and other hot products - it's just a matter of getting the newsletter out and finishing the update
That said, there is currently a little something in the works that should satisfy your itch. Check back around the beginning of December

To be brutally honest though - most "deal shopping" is eaten up by RFD who pretty much holds a monopoly on the whole thing, especially given the limited Canadian consumer reach. Stores would much rather put money there than a poky little hardware website
