The store was one of several new outlets Menards was planning in Missouri and Illinois. Menards issued a statement making the reason for it's change of heart clear:

“We are on schedule to open our new stores in O’Fallon, IL and St. Peters, MO this Spring, 2013.  For O’Fallon, MO, I’m very sorry, but we are a family owned business and with the Obama Administration scaring the dickens out of all small businesses in the USA at present, we have decided not to risk expansion until things are more settled.  Thank you for your patience and understanding.”
