San Francisco-based startup GoPago is a company on a mission: to bring an end to waiting in line. The company’s free mobile app–which just launched in S.F. in partnership with Chase—lets you order and pay for everything from coffee to burgers straight from your smartphone. You get to skip lines at local spots like Freshii and Tony’s Pizza Napoletana, because your order is ready and waiting when you arrive.

In celebration of its launch, GoPago is empowering several hundred “Super Heroes” to buy breakfast or lunch for everyone they know in San Francisco. GoPago’s team will be hanging out around the Financial District this week designating “Heroes.” Each Hero gets his/her own code redeemable for a $10 credit at hundreds of S.F. spots. The best part? For 48 hours, they can share those codes with their entire social network (from friends to co workers to Twitter followers).

Naturally we wanted to get our readers in on the action, so here’s our very own 7x7 code that you can enter into your GoPago app to score a free lunch before it expires on 6/2/12 at 9:00 a.m. Use code - Super7x7.

If you want the chance to hit up Sin City, we’ve got a stash of 20 Hero codes a day for those who want  to participate. Be the first person to use a code and you’ll be a Super Hero, no you won’t be in the next Avengers movie but you will be entered to win a trip for two to the Hard Rock Hotel and Casino in Las Vegas.  To win, you must share your code with the most people (see terms & conditions here).  All codes will be good for $10 in credit, but there will only be one Grand Prize Winner. Remember codes expire 48 hours after their first use!
