CNN just ran a story on their Money Report (Gerri Willis) of a manufacturer of the plastic patron saint, St. Joseph. The manufacturer is Lutheran, yet he says even he is impressed with the results this little plastic saint figurine is getting. St. Joseph is the patron saint of the home.
It seems you buy it, pray a prayer for the sale of your home, bury the saint head-down in your yard, and your house will sell. It was also reported this particular saint has a very close relationship with Mary, the mother of Jesus.
One desperate featured homeseller bought the saint, buried him and got an offer the next day.

But this was after he lowered the sales price of his house from $245K to $145K. I wonder which one really affected the receipt of the offer?
The story is not on the website, at least I have not located it to supply a source, but it is running on CNN.
