Only some notebooks are 50% off?

I don't understand. The coupon says 50% off notebooks but all of mine are only 15% off today. Is it only select items ithay are ncluded in the 50% off sale?

There's more than one "maker" for spiral notebooks. The Fuji notebooks do not appear to be on 50% sale, whereas the GottchaCovered ones are.
