Ordering Bricks

For some months now, we have had a "nominal order" of bricks on the books with our brick supplier. I have today, placed an order for the bricks to cover the base-brickwork (the bricks between footing and the damp-course). While I worked out the quantity pretty accurately, I have over-ordered slightly, as any bricks remaining can be used later on the top-brickwork. Bricks come in packs of 272-per-pack. I have allowed a three week delivery delay for this order.
