Summer may be over, but Groupon is still helping Chicago residents enjoy all the outdoor activities their city has to offer. For this reason, Groupon has just announced “Groupon Presents…”, a showcase of the best and most interesting local culture and entertainment to enjoy. “Groupon Presents…” will begin with a movie night at Wrigley Field to celebrate the 25th anniversary of classic movie “Ferris Bueller’s Day Off”. The screening will take place on Saturday, October 1, when a selection of great Chicago deals will also be on offer, including discounted admission to the SkyDeck at Willis Tower.
