DENVER — A Houston furniture store lost $7 million Sunday after running a Super Bowl promotion that would give big-spending customers their money back if the Seattle Seahawks won the game.

Jim “Mattress Mack” McIngvale said that he would give a refund to customers who spent $6,000 or more at Gallery Furniture in the two weeks leading up to the game, ABC News reported.

When the Seahawks throttled the Denver Broncos on Sunday, McIngvale confirmed he would deliver on his promise, giving back more than $7 million to about 1,000 customers.

“The accountant is pulling his hair out this morning, but the customers are happy and that’s what’s most important,” McIngvale told ABC News.

McIngvale says his accountant told him he was “crazy” for making the bet, but now he is confident it will pay off in the long run for his business.
