If you’re an American Express user and a pizza lover, Foursquare has a deal for you.

It’s safe to assume that plenty of people will order pizza during the Super Bowl. It’s also pretty safe to assume that a high percentage of that pizza will come from one of the country’s biggest delivery pizza chains, Pizza Hut. If you’re planing on ordering a Pizza Hut pizza during the game, don’t forget to check-in.

Starting a few hours before kickoff and running until the end of the game, you can check in a universal location called “Super Swarm Sunday” on Foursquare. When you do, make sure to unlock the $5 off Pizza Hut deal. Now, when you spend at least $10 at Pizza Hut, you’ll get a $5 credit on your AMEX card.

Here’s some FAQ about the event, from the Google+Reader”>Foursquare blog:

I don’t really care for football. Can I still check in?
Super Swarm Sunday isn’t just about football! Check in if you love the commercials, over-the-top halftime shows, the Puppy Bowl, touchdown salsa dances, or just hanging out and eating pizza with friends.

Where do I check in?
If you’re in the US, you’ll see Super Swarm Sunday when you tap ‘Check In’ on your app, starting a few hours before the game and lasting until the end of the night.

How do I unlock the Special?
Once you check in, you’ll be able to sync your American Express® Card to your foursquare account and load the Special (it takes a few seconds, and foursquare won’t store your information – we’re just providing the deal!). If you’ve synced your card before, just tap ‘Load to Card.’

How do I redeem the Special?
Spend at least $10 on your Pizza Hut order online, by phone, or in participating stores, and pay with your American Express® Card. The $5 credit will show up on your statement in a few days.

Do I need to mention the Special when I order from Pizza Hut?
Nope! It’s all taken care of by foursquare and Amex. As long as you pay with the card that you synced (and your order is over $10), you’ll see the credit on your statement in a few days.

This is one of Foursquare’s biggest check-in events ever. It’s name is a reference to a “swarm,” a Foursquare term for when you check-in with a lot of people at one location. You can earn badges for each level of swarm – 50 is a regular swarm, 250 is a super swarm, 500 is a super duper swarm, and 1000 is an epic swarm.

Badge lovers won’t be disappointed – checking in on Super Swarm Sunday will earn you a new badge. It looks like the other swarm badges but the little bees have been replaced by footballs.
