Universal Windows isn’t afraid to put their money where their mouth is.

The Cleveland-based company, who are celebrating their 15th anniversary, ran a promotion earlier this summer promising customers full refunds if the Indians went on a 15-game win streak at any point from August 1 until the end of the 2017 MLB season. Unfortunately for them, the Tribe beatdown the White Sox on Thursday night to record their 15th straight win, putting Universal Windows on the hook for $1.7 in refunds.

The company is taking it in stride though. They held a party at Progressive Field and celebrated both the streak and the free windows.

According to Darren Rovell of ESPN, the company won’t be completely on the hook for the $1.7 million in refunds. They spent $75,000 on an insurance policy that should cover most (if not all) of the promised refunds.

The Indians began winning on August 24 and haven’t stopped yet. The current streak of 15 games is the longest in franchise history and the longest in MLB since the Oakland A’s rattled off 20 in a row in 2002. The reigning American League champs will attempt to keep the streak alive on Friday night when they return home to start a series against the Baltimore Orioles.
