I can't speak for HD block, as I can buy concrete block locally here with far better options for FAR better pricing. There's really no such thing as a corner block on an 8" wide wall, just a flush end block. Typically, between 20-30% of 8" block on a pallet will be either single of double end flush block. Knowing how HD beats the heck out of their suppliers, they probably don't mix any flush block in at all..........
