Some folks had some difficulty figured out how to apply the codes to their blade and/or bit orders. I found this link for a guy who was having problems. Hopefully this helps for anyone getting the discount codes to work.

Note : As per my prior thread this code is working on some other products such as Bench Dog products, router lifts, etc. Freud dado sets seem like a great deal.
