Cash for gold

If, like me, you found yourself watching far too much daytime TV over the holidays, you may have noticed advert after advert imploring you to send your unwanted gold (even teeth!) to a company in return for cash. Interest in companies like this has soared during the recession as people struggle to cope. H. Samuel has just entered the market, hoping their recognised brand name will entice customers. Can any of your pupils think of other industries which will do well during a recession?
