This is a REALLY good deal for those of you in (or visiting) Oklahoma. Groupon is offering admission ticket to Science Museum Oklahoma and Imax movie, FOR TWO people for $12. Crazy good deal and way more than 50% off, but only on groupon for one day, May 18th. Just saw this, and it is too good a deal to pass up. If you haven't been to Science Museum Oklahoma, it is one of the best in the nation.
