We’ve seen retailers make a big gamble for events like the Super Bowl (and lose millions in merchandise, in one case), but this might be the first time we’ve caught wind of a car dealership willing togive out free cars just to woo Black Friday shoppers.

In what one Chicago-area Buick dealership is calling a “White Friday” sale, customers who buy any brand new Buick or GMC vehicle on Nov. 28 and 29 will have the chance to get all that money back come Christmas, reports the Chicago Tribune.

The catch is, it has to snow six inches or more on Christmas Day, a measurement that must be recorded at the O’Hare International Airport weather station.

The chances of getting any amount of snowfall in Chicago on that day are between 40% to 50%, according to the Illinois Climatologist office, much less an entire six inches.

Even so, if the dealership is smart, it’s got some kind of insurance policy backing this deal up.
