got a price adjustment on my 195/65/15 WS70s from Costco...i couldn't wait for the sale, so i bought them a couple of weeks ago and was told to just pop in for a price adjustment when they go on sale...the sale on Bridgestone Tires is now on...$70 off a set of 4 plus an additional $40 towards install, for a total savings of $110 plus taxes...all in, it was about $510...pretty good deal for a set of four WS70s installed/taxes in.
