Check in at a kiosk, and walk away with a discount: Redbox, which rents DVDs, Blu-ray discs, and video games from kiosks in more than 27,800 locations across the country, is running a discount promotion with location-based mobile app foursquare.

During the Redbox 10 Days of Deals campaign, which runs Aug. 15-24, foursquare users who check in at Redbox locations will unlock daily discount codes which will save them $0.10-$1 on transactions at the kiosks that day.

foursquare director of business development Eric Friedman said:

It’s exciting to see Redbox rewarding their millions of customers through the foursquare Specials platform. The Redbox 10 Days of Deals campaign is a great opportunity to introduce a huge group of consumers to the benefits of using foursquare.

And Redbox vice president of marketing Amy Gibby added:

With more than 27,800 locations nationwide, mobile allows Redbox to hyper-localize our engagement efforts. foursquare significantly expands our mobile touch points and unlocks new ways for consumers to engage with Redbox at local kiosks.
