A Super Bowl bet has cost a Houston furniture store owner $7 million after the Seahawks defeated the Broncos.

Jim "Mattress Mack" McIngvale said that he would give a full refund to customers who spent $6,000 or more at Gallery Furniture in the two weeks leading up to the game and had their orders delivered by 5pm on Sunday.

ABC affiliate KTRK first reported the story.

When the Seahawks delivered a victory on Sunday, McIngvale confirmed he would deliver on his promise with an announcement on the company's website declaring "Customers Win $7,000,000."

"The accountant is pulling his hair out this morning, but the customers are happy and that's what's most important," McIngvale said to ABC News.

McIngvale says while the accountant initially told him he was "crazy" for making the bet, he is confident it will pay in the long run for his business.

"It worked for making the customer say 'This guy does what he says he's going to do,'" McIngvale said.

He said over 1,000 customers will receive on average $7,000 in refunds from the promotion. He plans to deliver the refunds during a celebratory party at the store on Feb. 17.
