Affording tickets to live events often requires creative fundraising, including starting lemonade stands, searching couch cushions for spare change, and borrowing money from your child's piggy bank at a dubious interest rate. Avoid playing debt games with today's Groupon: for $40, you get a one-year Duet membership from Fillaseat.com (a $79.95 value).

Fillaseat.com's memberships transform couch potatoes into social butterflies with access to unlimited shows, concerts, night club and sporting events in the Las Vegas area, all without additional ticket fees. Rather than repurposing unused seats as rental office space, popular venues give extra tickets to the entertainment-loving interweb elves of Fillaseat.com to unleash on their waiting members. On the day of the event, members snap up tickets from 10 a.m. to 4 p.m. on a first-come, first-served basis. Each day brings new events and venues, giving members plenty of opportunities to indulge in one or two premium seats with enough cash left over to bribe a jumbotron camera operator for the unveiling of an intricately choreographed, solo patty-cake routine.
