Added the Precision Pro NX9 Slope into my cart the other day and the normal 15OFFTHP code worked but waited to see if any other Black Friday deals came about. Applied the 20% off coupon just now and the NX9 is now listed as discounts cannot be applied to this product. That stinks, might as well just go over to local shop and support them for the same price.
PP worked for another THP user the other day... Not sure it was 20%... Also $50 off on their website.
