Look, you're probably going to hit up McDonald's at least once this week. Might as well save some cash when you do.

It's pretty simple too.

All you really need is the McDonald's app. Don't worry it's free.

From there, just open up the McDonald's app daily and they will give you a coupon that marks down virtually any sandwich to just a dollar, except "Signature Crafted Recipe sandwiches and Double Quarter pounders with cheese" according to Foodbeast.

When you drive thru or order inside McDonald's just flash the QR code underneath the deal. The person behind the counter will zap the code and boom, you just a got a Big Mac for a buck.

The one dollar sandwich deal will expire September 30. You have two and a half months to eat one dollar burgers or sandwiches, so get ready.
