( CNN ) -- Beware learning American history through Groupon promotions . Contrary to what the online coupon company claims , Alexander Hamilton was never a U.S. president . The discounter put out a news release announcing `` Groupon Celebrates Presidents Day by Honoring Alexander Hamilton , '' and offering $ 10 off of all local deals above $ 40 . `` The $ 10 bill , as everyone knows , features President Alexander Hamilton -- undeniably one of our greatest presidents and most widely recognized for establishing the country 's financial system , '' the Business Wire release read . Hamilton , whose portrait does grace the $ 10 bill , was the first treasury secretary and is credited with laying the foundation of the U.S. financial system . But he was never president . When people suggested Groupon 's promotion was tongue-in-cheek , it responded through its Twitter account : `` Joke ? We 'd never joke about saving $ 10 ! # AllKindsOfSerious '' @ carmstrong07 was not convinced , tweeting : `` Gee whiz , it 's almost as if @ Groupon did something ridiculous to get everyone online talking about them . '' `` We 're shocked by this implication ! Shocked ! '' the company replied . In case Groupon decides to give a $ 100 discount next year , Benjamin Franklin -- the face on the C-note -- was never a U.S. president either .
