A Nissan dealer is offering customers who buy before August 1 a full refund if it rains on August 8.

World Nissan in Texas, USA, is running the promotion on all new Nissan Altimas sold during July.

New car sales manager Big Al Ortiz said the campaign is bringing people into the dealership.

The dealership has a $1 million insurance policy to cover the cost if more than two inches of rain is measured locally on August 8.

The odds are pretty long - central Texas is in the middle of a drought.
