We are planning on ripping out our large brick patio very soon and are gaging the interest in the used brick, thinking 25 cents per brick OBO. There will probably a few hundred of them. You would have to haul them, but there will be easy access from the alley.
So the bricks are standard red bricks and the dimensions are 8 1/4″x 4″ x 2 1/4″. I am trying to include a picture but not sure if I can on this forum. It is the kind of brick you think of for a fireplace, wall etc. not a paver.
