How much do you like burgers? Because Betty’s Burgers wants to give you a year’s supply of the things. For free. That’s $1560 worth of Betty’s for the grand total of absolutely nothing.

The promotion involves one $30 meal every week. So anything on the menu – burgers, fries, onion rings, concretes – is fair game up to the price.

The free burgers are to celebrate National Burger Day on Monday. And for such a generous prize, it’s relatively straightforward to enter: just snap a picture of you enjoying a burger from Betty’s between Friday May 25 and Sunday May 27 and post it to Instagram, along with the hashtag #yearofbettys and tagging @bettys_burgers. The most creative snap gets the mother lode.

Noosa’s Betty’s Burgers finally blew into Melbourne in 2016, setting up shop in the CBD. The offer is available from all other Betty’s stores throughout Australia.
