Travelzoo offers a FlexPass NYC 2-Attraction Sightseeing Pass for $49. (Groupon charges the same.) That's tied with last week's mention and the best price we could find by $15. Choose any two activities from a list of nearly 40 attractions, including Madison Square Garden, MoMA, Rockefeller Center, and the Empire State Building. Book this travel deal by March 31 for travel through the same date.
