Where to buy bricks

[terracore]

Home depot has cinder blocks. Walmart doesn't have real bricks (made of fired clay), and I'm not sure HD does either, but both have paver bricks (brick-sized concrete blocks dyed red). I saw fire bricks at HD *once*. If memory recalls, at HD the cinder blocks are by the concrete and the pavers are by the landscaping supplies outside. Walmart has both gray and red pavers next to the potting soil.
