Groupon is being called out for a Presidents Day promotion honoring Alexander Hamilton, the nation's first Treasury Secretary, but never a president.

Oops! Georgia Candidate Kicks Off Campaign for 'Govenor'

The cringe-inducing promo page referred to Hamilton as "undeniably one of our greatest presidents and most widely recognized for establishing the country's financial system." 

The deal featured a $10 bill, which shows Hamilton, and advertised that users would get 10 bucks off for $40 spent at a local business.

The company had a sense of humor about it though, with a spokesman responding, "We'll just have to agree to disagree."
