Sometimes it feels like you need superhero powers to get through your supermarket shopping.
But now, dressing up as your favourite superhero will let you become a real-life hero in a new breast cancer fundraising drive.
The NZ Breast Cancer Foundation and Pak'nSave have teamed up in the fight against the disease.
For the next seven days customers are being encouraged to go in-store dressed as their favourite superhero, snap a selfie to upload to Facebook, and a dollar will be donated to the cause.
Every uploaded photo will also go in a draw to win $1000 worth of groceries.
