Last year was in one of the "home" stores looking for ceramic tile for another "turtle" project. There was a basket filled with broken pieces, so I asked if they were for sale, either at a reduced price or even for free. Was told "no, they couldn't sell it," that they had to return the pieces to the vendor. I pressed it, then was told that if they sold or gave away a broken piece, that customer could bring it back to the store (or a different store), claiming that the store "sold them defective merchandise," asking for a refund.
I finally convinced them to let me have a couple of the pieces, but, geesh!
